Buttercream icing with flour
2 1/2 T flour
1/2 c milk
1/2 c butter or marge
1/2 c sugar

Blend flour and milk in saucepan till smooth. Cook over moderate heat, stirring constantly, till thickened. Cool. (mixture will be fairly stiff) Beat butter till creamy, add sugar gradually till light. Add the cooled flour mixture and beat at high speed till mixture is light and fluffy, about 1 to 2 minutes. Gently fold in vanilla. Makes enough to frost top of 9 inch square cake. Double for layer cake.
