I have a Duncan Hines Caramel Cake Mix and was thinking about making an apple dump cake with it. But then I noticed I have some pumpkin (homemade). I have seen cake mixes that you can just add pumpkin and mix it up, bake and you have a cake. My question is…...Could I do it similar to a dump cake? Apple pie filling in the bottom, then mix the caramel cake mix and pumpkin together and pour over the apples? And how long would I want to bake that? I’m thinking that would be a great combination of pumpkin, apple, and caramel! Just not sure how I would do it!
