This is a big, fat recipe, enough for 2 dozen cupcakes.

You will need: 

  • 8 tablespoons butter, at room temperature
  • 1/2 cup unsweetened cocoa powder
  • 3 cups confectioners’ sugar, sifted
  • 3 to 5 tablespoons milk
  • 1 teaspoon pure vanilla extract

Then you:
Place the butter and cocoa powder in a large mixing bowl. Blend with an electric mixer on low speed until the mixture is soft and well combined, 30 seconds. Stop the machine and add the confectioners’ sugar, 3 tablespoons of the milk, and the vanilla. Blend with the mixer on low speed until the sugar is incorporated, 1 minute. Increase the speed to medium and beat until light and fluffy, 1 minute more. Add 1 to 2 tablespoons more milk if the frosting is too stiff.
