1Preheat oven to 350 degrees. Lightly spray a 9x13 pan with pam.
2Open the cans of pie filling and spread them evenly in the bottom of the pan.
3Open the box of cake mix. Spread the dry cake mix over the top of all the apples. If using nuts, spread them over the cake mix.
4Melt the butter in the microwave.
Pour the butter over the top of the cake mix so that it will cover most of it.
5Bake about 40-45 minutes, until the top is lightly browned and the apples are bubbly. Cool in pan and serve warm or room temperature with vanilla ice cream or just plain. Refrigerate and it is even better the next day ice cold! Enjoy!
