Combine cake ingredients and make 6 small layers. Bake at 350'. Cool. Beat cream cheese, sugar, and cool-whip together. To assemble cake; spread cream cheese mixture on first layer, then 3 or 4 T. blueberrys. Continue till all layers are used. Press each layer firmly as they are added. Refrigerate for 24 to 48 hours before cutting. ------------------------------------------------------------------------NOTES : I make 3 layers and slice in half. (Bake time about 18 min.) Any flavor pie filling or crushed pineapple may be used.
