2 cans of pie filling (any flavor)
1 cube melted butter
1 dry cake mix (any flavor)
Spray cooker with cooking spray. Pour pie filling into cooker. Sprinkle cake mix on top and drizzle melted butter on top- try to cover as much of the cake mix as possible with butter. Cover and cook on high for 1-2 hours or low 3-4 hours, until cake starts to brown on the sides.
You can also mix cake with butter first then sprinkle over top or mix cake mix with 1 can of evaporated milk.
