Preheat the oven to 350℉.
In the cake pan, add the apple filling and spread it out evenly. Drizzle the caramel across the tops of the apples. Then, sprinkle all the cake mix on top of everything. Tip, if you'd like to add nuts or anything else, do it now before going to the next step.
Lastly, pour the melted butter across the top as evenly as possible. Bake the cake for 40-45 minutes then remove from the oven and allow to cool a bit before serving.
You can serve it warm with a scoop of ice cream, enjoy.
