Ingredients

For the Crust:

  • 1and ½ cups 180g graham cracker crumbs about 12 full-sheet graham crackers
  • ¼ cup 50g granulated sugar
  • 6 Tablespoons 85g unsalted butter melted

For the Brownies:

  • ½ cup 113g unsalted butter (melted)
  • 2 4- ounce quality semi-sweet chocolate bars 228g coarsely chopped
  • 1 cup 200g granulated sugar
  • 3 large eggs room temperature
  • 1 teaspoon pure vanilla extract
  • ½ cup 63g all-purpose flour (spooned & leveled)
  • ¼ cup 21g unsweetened natural or Dutch-process cocoa powder
  • ½ teaspoon salt

For the Marshmallow Meringue Frosting:

  • 3 large egg whites room temperature
  • ¾ cup 150g granulated sugar
  • teaspoon cream of tartar essential for stabilizing
  • 1 teaspoon pure vanilla extract

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
