Let’s Bake! Your Step-by-Step Cupcake Guide
Ready to tackle this fun and rewarding project? We’ll break it down into easy-to-follow parts.
Part 1: The Graham Cracker & Chocolate Crust
- Preheat and Prep: Preheat your oven to 350°F. Line two 12-cup standard muffin pans with paper liners.
- Make the Crumbs: In a food processor, pulse the graham crackers until they are fine crumbs. Add the sugar and melted butter and pulse a few more times until the mixture resembles wet sand.
- Create the Crust: Spoon about 2 teaspoons of the crumb mixture into the bottom of each muffin cup and press down gently to form a compact layer. Top each crust with 1 teaspoon of mini chocolate chips.
Part 2: The Moist Chocolate Cupcakes
- Mix the Batter: In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, and salt. In a separate medium bowl, whisk together the buttermilk, eggs, oil, water, and vanilla.
- Combine and Fill: Pour the wet ingredients into the dry ingredients and whisk until the batter is smooth. Spoon about ¼ cup of batter into each muffin cup, right on top of the chocolate chips.
- Bake and Cool: Bake for 20 to 25 minutes, until a wooden pick inserted into the center comes out clean. Let the cupcakes cool completely on a wire rack. This is crucial!
Part 3: The Fluffy Marshmallow Topping
- Heat the Egg Whites: In a large, heatproof metal bowl (like the bowl of your stand mixer), whisk together the egg whites, sugar, and cream of tartar. Place this bowl over a saucepan of simmering water, ensuring the bottom of the bowl does not touch the water.
- Dissolve the Sugar: Whisk the mixture constantly over the simmering water for 3 to 4 minutes, until it’s warm to the touch and the sugar has completely dissolved (it should feel smooth, not gritty, between your fingers).
- Whip to Stiff Peaks: Transfer the bowl to your mixer fitted with the whisk attachment. Beat on medium-high speed until the meringue is thick, billowy, bright white, and forms stiff, glossy peaks. This will take 5-7 minutes. Beat in the vanilla extract.
Part 4: Assemble and Toast!
- Pipe the Topping: Transfer the finished marshmallow topping to a piping bag fitted with a large round or star tip. Pipe a generous, tall swirl onto each of the completely cooled cupcakes.
- Get Torching!: Using a small handheld kitchen torch, carefully toast the marshmallow topping. Hold the flame a few inches away and keep it moving until you achieve your desired level of beautiful, golden-brown (and slightly charred!) toasty perfection. Serve and enjoy the oohs and aahs!

Notes
WiseRecipes’ Top Tips for S’mores Cupcake Success
These are the little details that ensure this impressive recipe turns out perfectly.
- Cool the Cupcakes Completely. This is the absolute most important rule. If you try to pipe the meringue topping onto a cupcake that is even slightly warm, it will melt and weep, creating a sad, soupy mess. Patience is your best friend.
- Ensure Sugar is Dissolved in Meringue. Before you start whipping your meringue, it is crucial that the sugar is fully dissolved in the warm egg whites. Any undissolved sugar will result in a gritty meringue instead of a silky-smooth one.
- Wipe Your Bowl Clean. Before making the meringue, wipe down your mixing bowl and whisk with a little vinegar. Any trace of fat or grease is the enemy of a stable meringue and can prevent your egg whites from whipping up properly.
- Master the Torch. A kitchen torch is a fun tool, but be safe! Use it in a clear, well-ventilated area away from anything flammable. Keep the flame moving constantly and a few inches away from the meringue to get an even, beautiful toast without burning it too quickly.
- Don’t Overmix the Cake Batter. For a tender chocolate cupcake, mix the batter only until the wet and dry ingredients are just combined. A few small lumps are okay. Overmixing develops gluten and leads to a tough cake.
Keep Them Fresh! Storing Your Toasted Masterpieces
These cupcakes are a wonderful treat to have on hand. Here’s how to store them.
- Storage: Due to the meringue topping, these cupcakes are best stored in a single layer in an airtight container at room temperature. They are at their peak on the day they are made but will stay fresh for up to 2 days. Refrigeration can make the cake firm and the topping a bit sticky.
- Freezing: You can freeze the unfrosted cupcakes beautifully. Once cooled, place them in a freezer-safe container for up to 3 months. Thaw at room temperature before frosting and torching. I do not recommend freezing the finished, frosted cupcakes.
FAQs: Your S’mores Cupcake Questions, Answered!
What is the topping? Is it buttercream?
No, it’s a Swiss meringue! It’s made by gently heating egg whites and sugar together before whipping them. This creates a topping that is incredibly light, airy, stable, and glossy—just like a perfect marshmallow. It’s much lighter and less sweet than a typical buttercream.
I don’t have a kitchen torch. Can I still make these?
You can! While the torch provides that signature campfire look and taste, you can also toast the cupcakes under your oven’s broiler. Place the piped cupcakes on a baking sheet and put them on a rack a few inches from the broiler element. Watch them LIKE A HAWK—they will go from golden to burnt in a matter of seconds. It will only take 30-60 seconds.
Can I make this as a layer cake?
Yes, this recipe would make a fantastic layer cake! Bake the cake batter in two 9-inch round pans (adjusting the baking time to 30-35 minutes). You can create the graham cracker crust in the bottom of the pans. Once cooled, fill and frost the cake with the marshmallow topping and toast the outside with your torch.
My meringue is runny and won’t form stiff peaks. What went wrong?
This is usually caused by a tiny bit of fat or grease in your mixing bowl, or a speck of egg yolk getting into your egg whites. Egg whites are very finicky. Make sure your bowl and whisk are impeccably clean, and be very careful when separating your eggs.
Final Thoughts: Your Favorite Campfire Treat, Reimagined
There is nothing quite like the joy of transforming a beloved, simple treat into an elegant and impressive dessert. These S’mores Cupcakes are a celebration of that idea. They are a fun, rewarding project that results in a truly special and delicious treat for sharing. I hope this recipe brings the fun of the campfire right into your kitchen. Happy baking!
