Chocolate Frosting

Ingredients:
1/2 cup butter, softened
2 2/3 cups powdered sugar, sifted
1/3 cup milk, un-whipped whipping cream, or half and half
1 1/2 tsp vanilla

Choose one of the following:
1/3 cup unsweetened cocoa powder, sifted (for light)
1/2 cup unsweetened cocoa powder, sifted (for medium)
3/4 cup unsweetened cocoa powder, sifted (for rich dark)

Directions:
Cream butter in a bowl.  Blend in the cocoa powder (as desired, above), vanilla, powdered sugar, and  milk.    Mix well until desired consistency is achieved.  You may need to add more milk if more cocoa powder is used.  Note: for more fluffy frosting, you can add 1 to 1 1/2 cups thawed cool whip topping at the end and beat on low until blended.
