1 cake mix
1/2 c. Crisco
3/4 c. Carnation milk
1 stick butter
1 c. sugar
1 tbsp. vanilla

Bake cake as on the box. Cool. Mix the remaining ingredients well. (It takes several minutes to mix.) Split the cooled cake. Spread the creamed mixture between the layers. Frost the cake. (This is similar to Twinkie or Hostess cup cake filling.)
