To make a cake with boxed cake mix and pie filling, combine 1 box of cake mix, 1 can of pie filling and 3 eggs in a bowl. Mix the ingredients, pour them into a greased cake pan and bake the cake for 30 minutes at 350 F.
The basic recipe can be varied in many ways by using different types of cake mixes and different varieties of pie filling to make the cake. For example, make a lemon blueberry cake with lemon cake mix and blueberry pie filling, or make a strawberry cake with a white or strawberry cake and strawberry pie filling.
For a different twist on the basic recipe, pour 1 can of apple pie filling in a greased baking dish, spreading it evenly on the bottom of the dish. Sprinkle the cake mix evenly over the apple pie filling, and top it with 1 stick of melted butter over the cake mix. Bake the cake for 45 minutes at 350 F. Remove it from the oven, and top it with a layer of mini marshmallows. Broil the cake for 30 seconds to toast the marshmallows.
Alternatively, make an easy fruit crisp by stirring 1/2 cup melted butter into 1 box cake mix. Add 1 can pie filling and 1 can of crushed pineapple to a baking dish. Top it with the cake mixture, and bake the crisp for 38 to 44 minutes at 350 F.
