Rich, thick, dark chocolate, and smooth - This frosting recipe is perfect for frosting cakes and cupcakes.
Using an electric mixer, beat the butter in a large bowl until smooth and creamy.
Add the icing sugar and cocoa alternately with the milk and vanilla until well incorporated, thick, and smooth.
If the mixture is too thick, add a little milk until it is a good spreading consistency.
Store in a sealed container until use. Makes about 3-1/2 cups of frosting, or enough for about 18 cupcakes.
