Fruit Magic (Like a Cobbler)

1 can pie filling (we like apple)
1 box Jiffy cake mix (9oz) (or 1/2 a box of yellow cake mix works too)
1 stick butter (I use 3/4 stick)
Nuts, chopped(optional)

Preheat  Oven to 350º. Grease a 9 inch pan (or similar). Pie filling on bottom, sprinkle dry cake mix on top. Cut butter into thin pieces and put on top of cake mix, add nuts. Bake 55 to 60 minutes. Cool, filling will be hot.
