I love this cake... just incase you haven't been to a Pampered Chef show in the last 10 years, I'll post the recipe :)
Mix 1 cake mix, 3 eggs and a can of pie filling. Poor into a stoneware fluted pan. Microwave 11 minutes. Turn out while still piping hot so it doesn't stick. Yummy!
Some of my favorite combos: pumpkin & spice cake, apple & butter pecan, cherry & chocolate.
Caution - remember your color blending. Blueberry & yellow cake = green... not so yummy looking.
