Cocoa-Cola Frosting

  1. In medium bowl, beat butter with electric mixer on medium to high speed for 30 seconds. Slowly add 2 cups powdered sugar and cocoa powder, beating until combined. Add cola, beating until combined. Gradually beat in 1-3/4 cups powdered sugar until combined. If necessary, beat in enough additional cola, 1 teaspoon at a time, to make frosting easy to spread.
