Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish with butter or non-stick spray.
Layer the Apple Pie Filling: Spread the apple pie filling evenly in the bottom of the prepared baking dish. Add the Cake Mix: Sprinkle the yellow cake mix evenly over the apple pie filling. Do not stir or mix it in.
Pour the Butter: Drizzle the melted butter evenly over the cake mix, ensuring it covers the top as much as possible. This will create a crispy topping as it bakes.
Add Optional Ingredients: If you want extra flavor, sprinkle ground cinnamon over the top. You can also add chopped nuts for added crunch and texture.
Bake the Cake: Place the baking dish in the preheated oven and bake for 45-50 minutes or until the top is golden brown and the apple filling is bubbling.
Drizzle with Caramel: Once baked, remove the cake from the oven and allow it to cool for a few minutes. Drizzle caramel sauce over the top just before serving. Serve: Serve the Caramel Apple Pie Dump Cake warm with a scoop of vanilla ice cream or whipped cream for added indulgence.
