1 yellow cake mix
5 tbsp. flour
1 c. milk
1/2 c. Crisco
1/2 c. butter
1/2 tsp. salt
1 tsp. vanilla
1 c. sugar

Bake 1 yellow cake mix in 9 x 13 inch pan. Cool. Split lengthwise (I use a jelly roll pan lined with wax paper and cut cake in half. Wax paper will peel off.) Cook until thick: 5 tablespoons flour and 1 cup milk, stirring constantly. Cool. Beat until fluffy: 1/2 cup Crisco, 1/2 cup butter, 1/2 teaspoon salt, 1 teaspoon vanilla, and 1 cup sugar. Stir flour mixture well. Slowly add to sugar. Beat until very fluffy. Use a small, deep bowl. Put filling between layers of cake and dust with powdered sugar. Refrigerate. Also good with chocolate cake for Suzy Q's.
