Directions

1. In a mixing bowl, beat cake mix, pudding mix and shortening on low speed until crumbly. Add the water and eggs; beat on medium for 2 minutes. Pour into a greased and floured 13-in. x 9-in. x 2-in. baking pan. Bake at 350 degrees F for 30-35 minutes or until a toothpick inserted near the center comes out clean. Cool for 10 minutes; invert onto a wire rack to cool completely.
2. Meanwhile, in a saucepan, combine flour and milk until smooth. Bring to a boil; cook and stir for 2 minutes or until thickened. Cool completely.
3. In a mixing bowl, cream the butter shortening, sugar, vanilla and salt; beat in milk mixture until sugar is dissolved, about 5 minutes. Split cake into two horizontal layers. Spread filling over the bottom layer; replace top layer. Cut into serving-size pieces. Garnish with raspberries if desired.
