Ingredients

Cupcake

  • 1 cup graham cracker crumbs (about 1 package)
  • ¼ cup unsalted butter
  • ¼ cup granulated sugar
  • 1 large egg, at room temperature
  • ½ cup buttermilk, at room temperature
  • ¼ cup vegetable oil
  • 2 teaspoon vanilla extract
  • ¾ cup all-purpose flour
  • ¾ cup granulated sugar
  • ½ cup cocoa powder
  • ¾ teaspoon baking powder
  • ¾ teaspoon baking soda
  • ½ teaspoon salt
  • ¼ cup hot brewed coffee

Marshmallow Frosting

  • 4 egg whites
  • 1 cup granulated sugar
  • ½ teaspoon cream of tartar
  • 1 teaspoon vanilla extract
  • graham cracker crumbs
  • Hershey's chocolate (optional)

Instructions

Cupcake

  • Preheat oven to 350°F and place 12 cupcake liners in a cupcake tin. Put graham crackers in a ziploc bag and crush with a rolling pin. In a medium bowl, add graham cracker crumbs, butter, and sugar and mix well.
  • Place a heaping tablespoon of the crust mixture in the bottom of each cupcake liner and press down. Bake crusts for 5 min. Remove and set aside to cool while you make the cupcakes.
  • Start making the cupcakes. In a stand mixer with paddle attachment, beat together the egg, buttermilk, vegetable oil and vanilla extract until smooth.
  • In a medium bowl, sift together the flour, sugar, cocoa powder, baking soda, baking powder and salt.
  • Add the flour mixture and mix on low speed until there are no longer any clumps. Add the coffee and mix until combined.
  • Pour the batter ⅔ full among the muffin tins and bake for 12-15 minutes or until a toothpick inserted into the center of a cupcake comes out clean. When cupcakes are done remove immediately from tins and leave on a cooling rack to cool completely before adding the frosting.

Marshmallow Frosting

  • Combine egg whites, sugar, and cream of tartar in a metal heat proof bowl. Place bowl over a saucepan with boiling water. Whisk constantly until sugar is melted and mixture is warm to touch or between 120°F and 140°F on a candy thermometer.
  • Remove from heat and pour into the bowl of an electric mixer. Using the whisk attachment, beat on a low speed gradually increasing to high speed until stiff, glossy peaks form, about 7-9 minutes. Add vanilla extract with 30 seconds left.
  • Spoon frosting into piping bag and pipe onto the cupcakes. Torch the frosting to add a roasted marshmallow look if desired and top with graham cracker crumbs.

Notes

  • Do not skip the buttermilk as it helps create the moistness you expect from chocolate cupcakes.
  • All refrigerated items should be at room temperature, which helps the batter mix easily and evenly. Also super important for the frosting.
  • When adding the batter to the muffin tin, don't fill more than ⅔ of the way as they do rise.
  • Separate your eggs into a smaller separate bowl so that if one of the yolks breaks for your frosting, you haven’t ruined the batch.
  • Pipe the frosting immediately as it sets quickly and becomes difficult to work with.
  • Allow the cupcakes to completely cool before adding the frosting, otherwise it will melt.
