Note: Today is my birthday. I really don't care what kind of cake the boys bake for me, but I would really love it if they would make this icing to go on top. It is my absolute favorite icing. Chocolate, rich, fudgy! I could eat it with a spoon.
1/3 cup butter or margarine
1/3 cup HERSHEY'S Cocoa
2-2/3 cups powdered sugar
1/3 cup milk
1 teaspoon vanilla extract
Melt butter in small saucepan over low heat; add cocoa, stirring constantly until smooth and slightly thickened. Remove from heat; pour into medium bowl. Cool until very thick (about 40 minutes).
Add powdered sugar alternately with milk and vanilla, beating to spreading consistency. About 2 cups frosting.
