Hot Chocolate Cupcakes
Yield: 24 cupcakes
for the cupcakes
  • 2 cups granulated sugar
  • 1¾ cups all-purpose flour
  • ¾ cup cocoa powder
  • 1½ teaspoons baking powder
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 2 large eggs
  • 1 cup buttermilk, see note
  • ¼ cup butter, melted
  • ¼ cup vegetable oil
  • 1 tablespoon vanilla extract
  • 1 cup hot coffee, see note
for the frosting
  • 2 cups unsalted butter, softened to room temperature
  • 4 cups marshmallow fluff
  • 2 cups powdered sugar
  • ¼ cup plus 2 tablespoons cocoa powder
  • Mini marshmallows, for topping
for the cupcakes
  1. Preheat the oven to 350 degrees F. Line two cupcake pans with cupcake liners so you have enough for 24 cupcakes.
  2. In a large mixing bowl or in the bowl of a stand mixer, sift together the sugar, flour, cocoa powder, baking powder, baking soda and salt.
  3. In a medium mixing bowl, whisk together the eggs, buttermilk, melted butter, vegetable oil and vanilla extract. Pour the liquid ingredients into the dry ingredients and mix together until smooth.
  4. Pour the hot coffee into the batter and stir until combined. The batter will be extremely liquidy. Divide the batter between the 24 cupcake liners, filling them slightly more than half full. Bake for 18-20 minutes, or until a toothpick inserted in the center comes back mostly clean. Alternatively, they are done when you gently press your finger on the center of a cupcake and it lightly springs back. I find mine to be done at exactly 19 minutes.
  5. Let cool in the pans for a couple minutes then remove to a wire cooling rack to cool completely before frosting.
for the frosting
  1. Beat the butter until fluffy, about 3 minutes, scrapping down the sides as needed. Add the marshmallow fluff, powdered sugar and cocoa powder. Beat until combined and fluffy, scrapping down the sides as needed. Pipe the frosting using a pastry bag (see note) and top with the mini marshmallows.
To make your own buttermilk: pour 1 tablespoon of lemon juice or vinegar in a liquid measuring cup. Pour milk, any fat percentage, into the measuring cup until you have 1 cup. Let sit for 5 minutes before using.
If you don’t want to use coffee you can use hot water, but the flavor of the chocolate won’t be as pronounced. You can use decaffeinated coffee if you prefer.
The frosting recipe is written assuming you will be piping a generous amount of frosting on each cupcake. If you would prefer to simply frost with a knife then you can most likely halve the frosting recipe.
