Viral 3-Minute S’mores Mug Cake
This is the exact dessert that’s setting TikTok, Instagram, and Pinterest on fire. You get everything you love about s’mores—without the campfire. Warm chocolate, gooey marshmallows, and crunchy graham bits in a soft cake base, ready in a microwave mug. Heaven.
Ingredients (Makes 1 serving)
- 2 tablespoons all-purpose flour
- 1 tablespoon unsweetened cocoa powder
- 1 tablespoon brown sugar
- 1 tablespoon granulated sugar
- ⅛ teaspoon baking powder
- Pinch of salt
- 2 tablespoons milk (any kind)
- 1 tablespoon neutral oil or melted butter
- 1 teaspoon vanilla extract
- 2 tablespoons mini chocolate chips or chopped chocolate
- 1 graham cracker, crushed
- 4–5 mini marshmallows (or 1 large cut in pieces)
Instructions
Step 1: Prepare the Mug
Choose a microwave-safe mug (8–10 oz). Lightly grease the inside with butter or spray to prevent sticking.
Step 2: Mix the Base
In the mug, combine flour, cocoa powder, both sugars, baking powder, and salt. Mix well with a fork.
Add milk, oil or butter, and vanilla. Stir until a smooth batter forms, scraping down the sides.
Fold in 1 tablespoon of chocolate chips.
Step 3: Add Toppings
Sprinkle half the crushed graham cracker over the batter.
Press 4–5 mini marshmallows gently into the center.
Sprinkle remaining chocolate and graham cracker crumbs on top.
Step 4: Microwave
Microwave on high for 1 minute and 15 seconds to 1 minute and 30 seconds, depending on your microwave’s wattage. The cake should rise, the marshmallows should puff, and the top should look set.
Don’t overcook it—the key to that gooey center is pulling it out before it gets dry.
Step 5: Cool and Serve
Let the mug sit for 1 minute (it’s hot!) before digging in.
Top with a dollop of whipped cream, a scoop of vanilla ice cream, or a drizzle of chocolate sauce if you’re feeling extra.
Pro Tips
- Want it richer? Swap milk for half-and-half or add a spoon of Nutella in the center before microwaving.
- No cocoa? Just skip it and add a bit more vanilla for a blondie-style version.
- No graham crackers? Use crushed digestive biscuits, shortbread, or even pretzels for crunch.
- Make it dairy-free: Use almond or oat milk and coconut oil instead of butter.
Other Quick Dessert Variations
- Peanut Butter Explosion: Add a teaspoon of peanut butter in the center before microwaving.
- Cookies & Cream: Stir in chopped Oreos instead of graham crackers.
- Salted Caramel S’mores: Drizzle store-bought caramel sauce on top before serving and finish with flaky salt.
Some trends are all fluff, but this one? Pure flavor gold. Whether it’s a late-night craving, a surprise treat for the kids, or your own self-care ritual, this 3-minute dessert is breaking the internet because it delivers. It’s fast, comforting, and customizable—and once you try it, you’ll keep coming back to it again and again. No cleanup. No oven. No regrets.
