Instructions
Preheat the oven to 350°F (177°C). Line two 12-count muffin pans with cupcake liners, one with 12 liners and one with 6 liners.
Make the crust: Grind the graham crackers into crumbs using a food processor, yielding about 1 and ½ cups. In a medium bowl, combine the crumbs, granulated sugar, and melted butter, stirring until evenly combined.
Spoon 1 and ½ Tablespoons of the crust mixture into each cupcake liner. Press down firmly to form a tight crust. Set aside.
Make the brownie batter: In a large heatproof bowl, melt the butter and chopped chocolate together. Use a microwave in 30-second bursts, stirring in between until smooth and fully melted.
Whisk in the granulated sugar and allow the mixture to cool slightly for 5 minutes.
Add the eggs, one at a time, whisking in between. Stir in the vanilla extract, all-purpose flour, cocoa powder, and salt. The batter will be thick.
Spoon the brownie batter into each cupcake liner, filling each almost to the top, right on top of the graham cracker crust.
Bake the brownie cups for 25–28 minutes, or until a toothpick inserted comes out with only a few moist crumbs (no wet batter). Begin checking at 22 minutes to prevent overbaking.
Remove from the oven and allow to cool completely in the pans before frosting.
Make the marshmallow meringue: In a heatproof bowl, combine the egg whites, sugar, and cream of tartar. Place the bowl over a saucepan with simmering water, ensuring the bowl doesn’t touch the water. Whisk constantly for about 4 minutes, until the sugar dissolves.
Use an instant-read thermometer to check that the mixture reaches 160°F (71°C). If not, continue whisking. Once the mixture reaches the correct temperature, remove from heat.
Add the vanilla extract, then use a handheld or stand mixer with a whisk attachment to beat on high speed for 5 minutes, until stiff, glossy peaks form.
Pipe the meringue onto the cooled brownie cupcakes using a piping tip (Ateco 808 recommended). Optionally, use a kitchen torch to lightly toast the meringue for that signature s'mores flavor.
Notes
These cupcakes bring the best of s'mores to life, with a decadent brownie base and a light marshmallow meringue topping. They’re perfect for a sweet treat on any day!
