Hershey's Chocolate Frosting

6 tablespoons butter or margarine, softened
1/3 cup cocoa
1/3 cup milk
1 teaspoon vanilla extract
2 2/3 cups confectioners' sugar

Cream butter in a small mixing bowl. Add cocoa and sugar alternately with milk. Beat to spreading consistency. Stir in vanilla extract. Adjust consistency if necessary with more milk or icing sugar.

Makes about 2 cups of frosting. Fabulous on a chocolate layer cake!
