Decorating frosting for cakes

1 cup softened butter
3  cups powdered sugar
2 T heavy cream
2 tsp vanilla

Whip butter, add cream, and flavoring. Add powdered sugar one cup at a time and mix until creamy and no lumps. That's all there is to it. It works great in all types of piping units and it does freeze well too.

To make chocolate frosting, mix 3/4 cup cocoa powder to powdered sugar.
