Ingredients for Pumpkin Dump Cake

Apple pie filling, spice cake mix, caramel nibs, cinnamon, chopped walnuts, and butter on a counter.
  • Pumpkin Puree – Make sure you are using real pumpkin puree. Don’t mistake it for pumpkin pie mix.
  • Pumpkin Pie Spice – Pumpkin fans love pumpkin pie spice. It is going to really give you that pumpkin flavor you want.
  • Cream Cheese Frosting – This is where the dump cake goes from tasty to decadent!
  • Walnuts – These are optional but add a nice texture to the cake.
  • Carrot Cake Mix – Buy cake mix at the store to use for this recipe. Any brand works.
  • Butter – Real butter is needed, no margarine.

Substitutions and Tips For Success

  • Swap the carrot cake with a yellow cake mix, spice cake mix, white cake mix, etc.
  • Serve this up at Thanksgiving dinner with a drizzle of caramel sauce on top.
  • Let the cake cool as it will help it to set up properly. The pumpkin pie filling is like a pumpkin pie at the bottom of the cake.
  • Use pure pumpkin puree not pumpkin pie mix in a can. They are not the same thing.
  • Sprinkle toffee bits in with the walnuts for a rich flavor to the cake. It would easily become a pumpkin crunch cake.
  • If you are a fan of pecans, use that instead.
  • Store cake in an airtight container or it will dry out the cake.
  • The cream cheese frosting helps to give this a pumpkin cheesecake flavor.

Storing Leftover Cake

Refrigerate – Any cake that is left needs to be refrigerated. You will find the cake spoils if left out at room temperature. Just place your cake in a covered dish and refrigerate for 3-5 days.

Freezing – If you want, you can freeze any leftover pumpkin pie cake. Simply freeze in a proper container for 2-3 months. Then thaw the cake in the fridge overnight before you plan to eat it.

Recipe FAQs

Why do you slice the butter thinly and place on top of the cake mix?

As the butter melts, it will help take the dry cake mix and transform it into a traditional cake. This pumpkin version dump cake is so simple to make, and the butter helps to create a light cake.

Is this like a traditional cakes?

Dump cakes are more like a cobbler style. The canned pumpkin gives this cake almost a soft pumpkin pie texture. Then you have the top layer, which is more cake-like. It is a very delicious recipe that makes for a great recipe.
