1 lb. butter
1 c. cocoa
2 tsp. vanilla
1 lb. Velveeta cheese
4 lbs. powdered sugar, sifted
1 c. walnuts

Melt butter and cheese together over low heat. Add cocoa and blend in. Beat in sugar in three parts. Add vanilla and walnuts. Stir over low heat until well blended. Pour into greased 2 (13 x 9-inch) pans. This will set up fast if allowed to cool while stirring.
