Preheat the oven to 350°F. Spray a 9x13 baking dish with cooking spray.
Spread the apple pie filling into the bottom of the baking dish.
Drizzle with the caramel sauce.
Cut the top of the yellow cake mix bag open and add the cinnamon and nutmeg. Stir it around inside the bag. Evenly sprinkle the cake mix on top of the apples and caramel.
Melt butter in a microwave safe bowl. Whisk with vanilla extract. Pour the butter mixture on top of the dry cake mix, trying to moisten as much as possible.
Bake for 45-50 minutes until bubbly and golden brown.
Let cool for 15 minutes. Serve with ice cream and more caramel sauce.

Notes
Any flavor of cake mix can be swapped for yellow. I really like spice cake, white or vanilla (which is basically yellow).
