Preheat and prepare: Preheat your oven to 350 degrees Fahrenheit and lightly grease a 9x13 inch baking dish.
Layer the filling: Pour both cans of apple pie filling into the prepared baking dish, spreading it evenly across the bottom.
Add caramel bits: Sprinkle the caramel bits evenly over the apple layer, distributing them throughout for consistent caramel flavor in every bite.
Mix the topping: In a small bowl, combine the dry yellow cake mix with the melted butter, stirring until the mixture resembles coarse crumbs.
Spread the topping: Pour and spread the cake mixture evenly over the apple and caramel layers, covering as much surface area as possible.
Bake: Place in the oven and bake for 30-35 minutes until the top is golden brown and a toothpick inserted into the cake portion comes out clean.
