Preheat your oven to 350°F (175°C).
Spray a 9x13-inch baking dish with non-stick cooking spray.
Spread both cans of apple pie filling evenly across the bottom of the dish.
Sprinkle caramel bits over the apples.
Evenly distribute the dry cake mix on top—don’t stir it in.
Lay the butter slices across the entire surface of the cake mix.
Bake for 45–50 minutes, or until the top is golden brown and bubbling.
Let it cool slightly before serving—if you can wait that long.
