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

Mix flour and milk; boil until thick then cool. After mixture has cooled, beat until fluffy, 10 to 15 minutes. Add rest of ingredients, beating well. Spread the filling between layers of cake. The longer beaten the fluffier it becomes.
