Craving a warm, homemade dessert but short on time? These 17 quick 3-ingredient mug cake recipes are your busy-night saviors. From chocolate fix to fruity indulgence, each single-serving treat is ready in minutes. Perfect for satisfying your sweet tooth without the fuss—just microwave and enjoy!

Classic Chocolate Mug Cake

Finally, a quiet afternoon calls for something sweet and simple. This classic chocolate mug cake, made with cocoa powder and self-rising flour, comes together in just one minute in the microwave. It's the kind of indulgence that feels both effortless and deeply satisfying.

Serving: 1 | Prep Time: 2 minutes | Cooking Time: 1 minutes

Ingredients

Dry Mix

3 tablespoons self-rising flour
2 tablespoons cocoa powder
2 tablespoons granulated sugar
Pinch of salt

Wet Mix

3 tablespoons milk
1 tablespoon vegetable oil
1/4 teaspoon vanilla extract

Instructions

In a microwave-safe mug, whisk together the self-rising flour, cocoa powder, sugar, and salt until evenly combined.
Add the milk, vegetable oil, and vanilla extract. Stir until the batter is smooth and no dry flour remains, making sure to scrape the bottom and sides of the mug.
Microwave on high for 50–60 seconds. Start checking at 50 seconds; the cake should be risen and set on top but still slightly moist. (Microwaves vary, so adjust time if needed.)
Let the mug cake cool in the microwave for 1 minute before removing. The residual heat will finish cooking the center.
Serve warm directly from the mug. For an extra-gooey center, undercook by 5–10 seconds.

How wonderful to have a warm, chocolatey hug in a cup. The cake is tender with a rich cocoa flavor, perfect for a cozy evening. Top with a scoop of vanilla ice cream or a drizzle of caramel for an extra treat.

Vanilla Bean Mug Cake

Keeping things simple yet special, this Vanilla Bean Mug Cake is my go-to when I crave something warm and sweet without the fuss of a full dessert.

Serving: 1 | Prep Time: 5 minutes | Cooking Time: 2 minutes

Ingredients

Dry Ingredients

1/4 cup self-rising flour
2 tablespoons granulated sugar
1 pinch salt

Wet Ingredients

3 tablespoons milk
2 tablespoons unsalted butter, melted
1/2 teaspoon vanilla extract
1/4 teaspoon vanilla bean paste (or seeds from 1/2 vanilla bean)

Instructions

In a microwave-safe mug, whisk together self-rising flour, sugar, and a pinch of salt.
Add milk, melted butter, vanilla extract, and vanilla bean paste. Stir gently with a fork until just combined—lumps are fine, but avoid overmixing to keep the cake tender.
Microwave on high for 1 minute 30 seconds to 2 minutes. The cake should be puffed and set on the surface, with a slightly moist center. Tip: timing varies by microwave wattage; start checking at 1 minute 15 seconds to prevent drying.
Let the mug cake cool in the microwave for 1 minute. The residual heat will finish cooking the center without overdoing the edges.
Carefully remove the mug (it will be hot). Tip: run a knife around the rim to loosen if desired, or enjoy straight from the mug for a cozy feel.

Cradled in the warmth of the mug, each spoonful is tender, fragrant with real vanilla, and delightfully simple. I love to serve it with a small scoop of vanilla ice cream that melts into every bite.

Peanut Butter Mug Cake

You know those evenings when only something warm and softly sweet will do? This peanut butter mug cake feels like a hug in a cup—creamy, nutty, and made in minutes with just a handful of staples.

Serving: 1 | Prep Time: 2 minutes | Cooking Time: 1 minutes

Ingredients

For the mug cake

3 tbsp self-rising flour
2 tbsp peanut butter
2 tbsp milk
1 tbsp sugar
1/2 tsp vanilla extract
Pinch of salt

Instructions

In a microwave-safe mug (at least 12 oz to prevent overflow), combine self-rising flour, sugar, and salt.
Add peanut butter, milk, and vanilla. Stir until just combined—no dry spots remain. For easier mixing, warm the peanut butter slightly first.
Microwave on high for 45 seconds to 1 minute. The cake should be risen and set on top but still slightly gooey in the center. Start with 45 seconds and check, as microwave strengths vary.
Let cool for 1 minute before eating directly from the mug. The cake will continue to set as it rests.

Your spoon sinks into that impossibly tender crumb, the peanut butter taste mellow and rich. I love dotting the warm cake with dark chocolate chips or a sprinkle of flaky salt—it turns simple into sublime.

Lemon Mug Cake

Some afternoons call for a tiny, bright lift — a warm, citrusy hug in a mug. This lemon mug cake is that moment: quick, simple, and deeply satisfying. The zesty scent alone feels like a pause button.

Serving: 1 | Prep Time: 2 minutes | Cooking Time: 1 minutes

Ingredients

For the mug cake

3 tbsp self-rising flour
2 tbsp granulated sugar
2 tbsp milk (any kind)
1 tbsp fresh lemon juice
1 tbsp vegetable oil or melted butter
1/2 tsp lemon zest (optional)

For the glaze (optional)

2 tbsp powdered sugar
1 tsp fresh lemon juice

Instructions

In a microwave-safe mug (at least 12 oz capacity), whisk together the self-rising flour and granulated sugar until combined.
Add the milk, fresh lemon juice, oil, and lemon zest (if using). Stir gently with a fork just until the batter is smooth — avoid overmixing to keep the cake tender.
Microwave on high for 50–60 seconds. The cake will rise and the top should look set and slightly springy to the touch. Microwave strengths vary, so start at 50 seconds and add 10 seconds if needed; do not overcook or it will become dry.
For the glaze: In a small bowl, stir the powdered sugar and lemon juice until smooth. If too thick, add a drop more juice; if too thin, add more sugar. Drizzle over the warm cake.
Let the cake cool in the mug for 1–2 minutes before eating — it will finish setting and the flavors will bloom.

How lovely it is when something so small tastes so complete. The crumb is tender, almost like a lemon muffin top, and the glaze adds a sweet-tart shimmer. Eat it straight from the mug with a small spoon, or top with a dollop of whipped cream for extra comfort.

Strawberry Mug Cake

Under the soft glow of my kitchen light, I find myself reaching for a mug and a spoon, craving something warm and sweet without a trip to the store. This strawberry mug cake, relying on pantry staples like strawberry jam and self-rising flour, delivers that fruity comfort in under two minutes.

Serving: 1 | Prep Time: 2 minutes | Cooking Time: 1 minutes

Ingredients

For the mug cake

4 tablespoons self-rising flour
3 tablespoons whole milk
2 tablespoons strawberry jam
1 tablespoon vegetable oil

Instructions

In a large microwave-safe mug (at least 12 ounces), whisk together the self-rising flour, milk, strawberry jam, and vegetable oil until just combined. A few small lumps are fine—overmixing will activate gluten and make the cake dense.
Microwave on high for 60 seconds. The batter should rise significantly and the top should appear set and slightly springy. If the center is still wet, microwave in 10-second bursts, checking after each. Microwave wattages vary, so adjust timing as needed.
Let the mug sit inside the microwave for 30 seconds to finish cooking from residual heat. Then remove carefully (the mug will be hot) and cool for 1 minute before eating. This resting step ensures a tender, not gummy, texture.
For a finishing touch, dollop an extra teaspoon of strawberry jam on top—it will melt into a luscious sauce. Serve immediately, straight from the mug.

Lifting the spoon, I break through the soft, cakey top to reveal a pocket of warm strawberry jam that mingles with the tender crumb. It's a cozy, no-fuss dessert that feels like a small hug on a quiet evening.

Cinnamon Sugar Mug Cake

On quiet evenings when a full cake feels like too much, this cinnamon sugar mug cake becomes the perfect little comfort. It’s soft, warmly spiced, and ready in just minutes—like a hug in a mug.

Serving: 1 | Prep Time: 5 minutes | Cooking Time: 1 minutes

Ingredients

For the cake

4 tablespoons self-rising flour
3 tablespoons granulated sugar
1/8 teaspoon ground cinnamon
3 tablespoons milk
2 tablespoons vegetable oil
1/4 teaspoon vanilla extract

For the topping

1 tablespoon granulated sugar
1/4 teaspoon ground cinnamon

Instructions

In a small bowl, whisk together 4 tablespoons self-rising flour, 3 tablespoons granulated sugar, and 1/8 teaspoon ground cinnamon.
Add 3 tablespoons milk, 2 tablespoons vegetable oil, and 1/4 teaspoon vanilla extract. Stir until just combined—overmixing can make the cake tough.
In a separate tiny bowl, mix 1 tablespoon granulated sugar with 1/4 teaspoon ground cinnamon for the topping.
Pour the cake batter into a microwave-safe mug (at least 12 oz capacity to allow room for rising). Sprinkle the cinnamon-sugar topping evenly over the batter.
Microwave on high for 45 seconds to 1 minute. The cake should look set and spring back lightly when touched; a toothpick inserted should come out clean. Cooking times vary, so start checking at 45 seconds.
Let the mug cake cool for 1 to 2 minutes—it will continue to set and the flavors will meld.

Nothing compares to the warm, tender crumb and the cinnamon-sugar crust that crackles softly as you dig in. Serve it straight from the mug with a scoop of vanilla ice cream, or dust with extra cinnamon sugar for a cozy finish.

Coconut Mug Cake

Kindled by a quiet craving for something tropical, I find myself reaching for a mug and a handful of pantry staples. This coconut mug cake is a gentle, last-minute dessert that feels like a small escape.

Serving: 1 | Prep Time: 5 minutes | Cooking Time: 1 minutes

Ingredients

Dry ingredients

2 tablespoons self-rising flour
1 tablespoon granulated sugar
1 tablespoon shredded coconut

Wet ingredients

2 tablespoons milk
1 tablespoon vegetable oil
1/4 teaspoon vanilla extract

Instructions

In a microwave-safe mug (at least 12 oz), whisk together the self-rising flour, sugar, and shredded coconut until evenly combined.
Add the milk, vegetable oil, and vanilla extract to the dry ingredients. Stir with a fork or small whisk until just moistened—no dry streaks remain, but be careful not to overmix.
Microwave on high for 45 seconds. Check for doneness: the top should be set and spring back lightly when touched. If still wet in the center, microwave in 15-second increments until done. (Tip: Microwaves vary, so start with 45 seconds and adjust.)
Let the mug cake cool for 2 minutes before eating. It will continue to cook slightly from residual heat. (Tip: For an extra-chewy texture, sprinkle a few more shreds of coconut on top before microwaving.)

Unwrapping the warm mug, I breathe in the sweet aroma of toasted coconut. The cake is tender, with little chewy pockets from the shredded coconut—like a soft, cloud-like bite of the tropics. Serve it plain, or top with a spoonful of yogurt or a drizzle of honey for a touch more sweetness.

Mocha Mug Cake

Perhaps there's no better way to treat yourself on a quiet afternoon than with a warm, gooey mocha mug cake. The gentle aroma of coffee and chocolate fills the kitchen as it bakes in under a minute, offering a small moment of solace. No fuss, just a soft, fudgy indulgence that feels like a secret you get to keep.

Serving: 1 | Prep Time: 2 minutes | Cooking Time: 1 minutes

Ingredients

Dry ingredients

¼ cup all-purpose flour
2 tablespoons granulated sugar
1 tablespoon unsweetened cocoa powder
1 teaspoon instant coffee granules
⅛ teaspoon baking powder
tiny pinch of salt

Wet ingredients

3 tablespoons milk (any kind)
2 tablespoons vegetable oil
¼ teaspoon vanilla extract
1 tablespoon chocolate chips (optional)

Instructions

In a microwave-safe mug (about 12 oz capacity), combine the flour, sugar, cocoa powder, instant coffee granules, baking powder, and salt. Stir with a fork until completely blended—make sure there are no lumps. Tip: Sift directly into the mug if you want an ultra-smooth texture.
Add the milk, vegetable oil, and vanilla extract to the mug. Stir gently with a small whisk or fork until just combined. Do not overmix; a few tiny lumps are fine. For a richer mocha, dissolve the coffee granules in the milk first before adding the other wet ingredients.
If using, sprinkle the chocolate chips evenly over the top and press them in slightly. This creates little pockets of melted chocolate.
Microwave on high for 45–60 seconds. Start checking at 45 seconds: the cake should be puffed and set on the surface but still slightly soft in the center. Cooking times vary by wattage; a 1000W oven usually needs about 55 seconds. Tip: If you prefer a fudgier texture, undercook slightly; for a drier cake, add 5–10 seconds.
Let the mug cake cool in the microwave or on the counter for 1 minute before eating. The residual heat will finish cooking the center. Be careful—the mug gets very hot! Use a towel or oven mitt to handle it.

Rich and deeply chocolatey with a gentle coffee whisper, this cake is impossibly moist and almost pudding-like at the center. Serve it straight from the mug with a dollop of whipped cream or a scoop of vanilla ice cream for a cozy dessert that feels like a treat, not a chore.

Blueberry Mug Cake

Cooking a single-serving cake in a mug feels like a quiet act of self-care on a busy afternoon. This blueberry jam-swirled mug cake comes together in minutes using just a few pantry staples, offering a warm, fruity treat that’s surprisingly antioxidant-rich. The jam not only adds sweetness but also creates beautiful pockets of tartness.

Serving: 1 | Prep Time: 5 minutes | Cooking Time: 2 minutes

Ingredients

For the cake base

1/4 cup self-rising flour
3 tablespoons milk
2 tablespoons blueberry jam

For the mug

1 teaspoon butter or nonstick cooking spray

Instructions

Start by greasing a microwave-safe mug with a teaspoon of butter or a quick spritz of nonstick spray. This ensures the cake releases easily.
In a small bowl, combine the self-rising flour and milk. Use a fork to whisk until just smooth — be careful not to overmix, as that can make the cake dense.
Pour the batter into the prepared mug, scraping the bowl clean.
Drop the blueberry jam by small spoonfuls over the batter. Then take a knife and swirl it through just three or four times to create a marbled effect without fully incorporating the jam.
Place the mug in the microwave and cook on high for 1 minute 30 seconds to 2 minutes. The cake is done when it’s puffed up, the center is set, and it springs back lightly when touched. Start checking at the earliest time to avoid overcooking.
Let the mug cake cool in the microwave for 1 minute before handling. The jam will be extremely hot, so give it a moment to cool down to safe eating temperature.

Holding the warm mug in your hands, you'll notice the cake is tender and moist, with pockets of sweet-tart blueberry jam that burst with every bite. Serve it as is for a quick dessert, or elevate it with a scoop of vanilla ice cream or a dollop of whipped cream. The contrast of warm cake and cold ice cream is simply delightful.

Pumpkin Spice Mug Cake

Oftentimes, a simple mug cake is all it takes to satisfy a seasonal craving, even in late spring. Today, with a chilly breeze outside, I'm reaching for warm pumpkin spice vibes—this mug cake is my little moment of comfort.

Serving: 1 | Prep Time: 2 minutes | Cooking Time: 1 minutes

Ingredients

Dry Ingredients

4 tbsp self-rising flour
3 tbsp granulated sugar
1/2 tsp pumpkin pie spice

Wet Ingredients

3 tbsp pumpkin puree
3 tbsp milk (any kind)
1 tbsp vegetable oil
1/4 tsp vanilla extract

Instructions

In a microwave-safe mug (at least 12 oz capacity), whisk together the self-rising flour, sugar, and pumpkin pie spice until well combined.
Add the pumpkin puree, milk, vegetable oil, and vanilla extract to the mug. Stir gently with a fork until just combined—overmixing can make the cake tough. Tip: Be gentle to keep it tender.
Microwave on high for 60 to 90 seconds, depending on your microwave wattage. Start with 60 seconds; the cake should be set on top and spring back lightly. If still wet in center, microwave in 10-second bursts. Tip: Every microwave varies, so watch closely.
Let the mug cake cool for 1 minute before eating—it will continue to cook slightly and set. Tip: Use a pot holder as the mug will be hot.
Serve straight from the mug, or invert onto a small plate if desired. Top with whipped cream or a dusting of extra pumpkin pie spice for a cozy finish.

Out comes a moist, fluffy cake with deep pumpkin spice warmth, like fall in a mug. The crumb is tender and just sweet enough. I love adding a dollop of whipped cream and a sprinkle of cinnamon—it feels like a gentle hug on a cool day.

Chocolate Peanut Butter Mug Cake

Reaching for a warm, indulgent treat that doesn’t demand much effort feels like a small act of self-care. This chocolate peanut butter mug cake is my go-to when I need something sweet, satisfying, and ready in minutes. The combination of rich cocoa and creamy peanut butter creates a decadent duo that feels both luxurious and comforting.

Serving: 1 | Prep Time: 5 minutes | Cooking Time: 1 minutes

Ingredients

For the mug cake base

3 tablespoons all-purpose flour
2 tablespoons unsweetened cocoa powder
2 tablespoons granulated sugar
1/4 teaspoon baking powder
Pinch of salt
3 tablespoons milk (any kind)
1 tablespoon vegetable oil
1/4 teaspoon vanilla extract

For the peanut butter swirl

1 tablespoon creamy peanut butter
1 teaspoon honey (optional)

Instructions

In a microwave-safe mug (at least 12 oz), whisk together the flour, cocoa powder, sugar, baking powder, and salt until no lumps remain. Be thorough—this ensures an even rise.
Add the milk, vegetable oil, and vanilla extract to the mug. Stir gently with a fork until just combined. A few small lumps are okay; overmixing can make the cake tough.
In a small bowl, mix the peanut butter and honey (if using) until smooth. Drop the mixture into the center of the batter, then use a knife to create a gentle swirl. Don't over-swirl—you want distinct pockets of peanut butter.
Microwave on high for 45 seconds to 1 minute. Start checking at 45 seconds; the cake should be puffed and set on top but still slightly soft in the center. Cooking times vary by microwave wattage.
Let the mug cake rest for 1 minute before eating. This allows the crumb to settle and the peanut butter to become molten. Be careful—the mug will be hot.

Let the mug cake cool just enough so the top becomes slightly fudgy and the peanut butter stays oozy. Each spoonful is a balance of rich chocolate, nutty creaminess, and a hint of salt—pure comfort in a cup. For an extra treat, top with a scoop of vanilla ice cream or a drizzle of warm chocolate sauce.

Gluten-Free Chocolate Mug Cake

Curling up on the couch with a warm mug cake in hand feels like the coziest indulgence. This gluten-free chocolate version is impossibly fudgy, made with simple pantry staples, and ready in just minutes. It's my little secret for those quiet evenings when only chocolate will do.

Serving: 1 | Prep Time: 5 minutes | Cooking Time: 1 minutes

Ingredients

For the Mug Cake

2 tbsp unsweetened cocoa powder
1 tbsp almond flour
1 tbsp granulated sugar (or coconut sugar)
1/4 tsp baking powder
1 pinch salt
2 tbsp milk (any kind, unsweetened)
1 tbsp melted coconut oil (or unsalted butter)
1/2 tsp vanilla extract

Optional Topping

1 tbsp chocolate chips (dairy-free if needed)
1 tbsp chopped nuts or a dusting of powdered sugar

Instructions

In a microwave-safe mug (about 10–12 oz capacity), whisk together the cocoa powder, almond flour, sugar, baking powder, and salt until no lumps remain.
Add the milk, melted coconut oil, and vanilla extract. Stir until the batter is smooth and well combined. *Tip: Make sure the coconut oil is warm but not hot to avoid cooking the batter prematurely.*
If using, fold in chocolate chips or nuts at this point for extra texture.
Microwave on high for 60–90 seconds. Check at 60 seconds: the cake should be puffed and slightly set on top but still look a little moist in the center. *Tip: Microwaves vary—start with 60 seconds to ensure a fudgy, not dry, cake.*
Let the mug cake cool for 1–2 minutes before eating. *Tip: It will continue to set as it cools, so resist the urge to dig in immediately.*
Top with a sprinkle of powdered sugar or a scoop of vanilla ice cream if desired. Serve warm.

Cradling this mug cake in my hands, I love how the edges are slightly chewy while the center stays soft and almost molten. It's a deeply chocolatey, flourless little hug in a cup—perfect on its own or dressed up with a dollop of whipped cream and a few raspberries for brightness.

Vegan Vanilla Mug Cake

Kind mornings call for a quick, comforting treat that feels like a hug in a mug. This vegan vanilla mug cake comes together in minutes with simple pantry staples, and the soft, fluffy texture will make you forget it's egg-free and dairy-free. It's the perfect little indulgence when you need something sweet but don't want to bake a whole cake.

Serving: 1 | Prep Time: 2 minutes | Cooking Time: 1 minutes

Ingredients

Dry ingredients

1/4 cup self-rising flour
2 tablespoons granulated sugar
1/8 teaspoon salt

Wet ingredients

3 tablespoons unsweetened plant-based milk (such as almond or oat)
1 tablespoon melted coconut oil
1/2 teaspoon vanilla extract

Instructions

In a microwave-safe mug (at least 12 oz capacity), whisk together the self-rising flour, sugar, and salt until well combined.
Add the plant-based milk, melted coconut oil, and vanilla extract. Stir gently with a fork until just combined—be careful not to overmix, as that can make the cake tough. A few small lumps are fine.
Make sure the batter is level in the mug. Tap the mug on the counter a few times to release any air bubbles, which helps the cake rise evenly.
Microwave on high for 60 seconds. The cake should look set on top and spring back lightly when touched. If it's still wet in the center, microwave in 10-second increments until done. Microwave times vary; start checking at 50 seconds if your microwave is over 1000W.
Let the mug cake cool for 1-2 minutes before eating—it will continue to set and will be very hot right out of the microwave.
For a fluffier texture, you can add 1/2 teaspoon of apple cider vinegar to the milk before mixing (it activates the leavening), but it's optional.

Each spoonful reveals a tender, moist crumb with a comforting vanilla warmth. The subtle richness from the coconut oil pairs beautifully with the light sweetness, making it feel indulgent without being heavy. Enjoy it right from the mug, or dress it up with a dollop of coconut whipped cream and fresh berries for an extra-special moment.

Optional Toppings

In a small bowl, beat the egg, then stir in melted butter and vanilla extract.
Pour the wet ingredients into the mug with the dry ingredients. Stir gently with a fork until just combined—do not overmix, as this can make the cake tough.
If using, fold in sugar-free chocolate chips evenly into the batter.
Microwave on high for 60 seconds. Tip: Microwave power varies; the cake should be set on top but still slightly moist in the center. Tip: Let it rest in the mug for 1 minute after cooking—it continues to firm up. Tip: Test doneness with a toothpick; it should come out with a few moist crumbs, not wet batter.
Top with whipped cream if desired. Enjoy immediately while warm.

Ultimately, this mug cake is a reminder that keto doesn't mean deprivation. The texture is tender and moist, with a deep chocolate flavor that satisfies every craving, and the slight crunch of chocolate chips makes it feel truly decadent.

Microwave on high for 60-70 seconds, until the cake rises and is set on top. Use a large mug to prevent overflow. Tip: Microwave times vary; start with 60 seconds and add 10-second bursts if needed.
Let cool for 1 minute before enjoying. Tip: For a gooey center, undercook slightly by reducing microwave time by 5-10 seconds.

Banana Mug Cake

Nothing quite compares to the comfort of a warm, single-serving dessert when you need a little sweetness to end your day. This banana mug cake is my go-to for those quiet evenings when I want something homemade but not a whole batch.

Serving: 1 | Prep Time: 5 minutes | Cooking Time: 1 minutes

Ingredients

Wet Ingredients

1 ripe banana, mashed (about 1/2 cup)
2 tablespoons milk (any kind)
1/4 teaspoon vanilla extract

Dry Ingredients

1/4 cup self-rising flour
pinch of salt

For the mug

butter or nonstick spray for greasing

Instructions

Lightly grease a standard microwave-safe mug with butter or nonstick spray to prevent sticking.
In a small bowl, mash the ripe banana thoroughly with a fork until smooth. A few small lumps are fine—they add texture.
Stir in the milk and vanilla extract until well combined. Use room-temperature milk for a more even batter.
Add the self-rising flour and salt to the wet mixture. Stir gently just until no dry streaks remain; overmixing can make the cake tough.
Pour the batter into the prepared mug. Do not fill more than halfway—it will rise in the microwave.
Microwave on high for 1 minute. Check for doneness: the top should be set and spring back lightly when touched. If still wet, microwave in 15-second bursts until done. Cooking times vary; start with 1 minute.
Let the mug cake cool for 1 minute before eating. The residual heat continues to cook the center slightly.

Scoop it straight from the mug for a cozy treat, or top with a dollop of yogurt or a drizzle of honey for extra indulgence. The moist, tender crumb and natural banana flavor will make you forget it came from a mug—though the simplicity is the real charm.

S’mores Mug Cake

Nothing compares to the nostalgic joy of a campfire s'more, but this mug cake version brings that gooey magic to your kitchen in just minutes. The soft, fudgy cake paired with melted marshmallow and chocolate is pure comfort on a quiet evening.

Serving: 1 | Prep Time: 5 minutes | Cooking Time: 1 minutes

Ingredients

For the crust

1 tbsp vegetable oil
1/4 tsp vanilla extract

For the topping

In a microwave-safe mug (about 12 oz), combine graham cracker crumbs and melted butter. Press the mixture firmly into the bottom of the mug to form an even crust.
In a small bowl, whisk together flour, sugar, baking powder, and salt. Add milk, vegetable oil, and vanilla extract; stir until just combined. Do not overmix.
Pour the batter gently over the graham cracker crust in the mug.
Microwave on high for 45 seconds to 1 minute. The cake should look set on top but still slightly moist; a toothpick inserted in the center should come out clean or with a few crumbs. Tip: Start checking at 45 seconds, as microwaves vary in power.
Immediately sprinkle the milk chocolate chips evenly over the hot cake.
Place the marshmallows on top of the chocolate chips. Microwave for 10–15 seconds, until the marshmallows puff up and start to melt. Tip: Watch carefully to prevent overflow—they can expand quickly.
Let the mug cake cool for 1 minute before serving. The marshmallows will be extremely hot. Tip: Use a spoon to scoop out the gooey topping, and enjoy the campfire flavor without the fire.

One bite of this warm, fudgy cake with melted marshmallow and chocolate brings back all those campfire memories. The soft cake contrasts beautifully with the chewy, toasted marshmallow top—perfect for a solo treat or a late-night craving.
