Ingredients
3/4 cup all-purpose flour
3/4 cup sugar
1 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
6 tablespoons unsweetened cocoa powder
3 tablespoons unsalted butter, melted
6 tablespoons buttermilk
1 large egg, plus 1 large egg white
Vanilla Cream-Cheese Frosting
Preparation
Preheat oven to 350 degrees. Line three 12-cup mini muffin trays with paper liners. In a large mixing bowl, combine flour, sugar, baking powder, baking soda, and salt; set aside.
With an electric mixer, combine cocoa and 3 tablespoons hot water until a thick paste forms. Add butter, buttermilk, egg, and egg white; beat until combined. Whisk in flour mixture until smooth.
Transfer batter to prepared tins. Each cup should be about 2/3 full. Bake until a toothpick inserted into the center of a cupcake comes out clean, 12 to 15 minutes. Transfer cupcakes to a wire rack to cool completely.
Use an offset spatula or butter knife to spread icing over tops. Decorate as desired.
