What is a Dump Cake?
A dump cake is an easy dessert made by layering or combining ingredients in a baking dish and topping them with dry cake mix and butter. Unlike a traditional cake, there is no separate batter to prepare. In this version, the pumpkin filling is mixed first, poured into the pan, and topped with dry spice cake mix and melted butter.
Ingredients
Gather the ingredients below to make this Pumpkin Dump Cake with Cake Mix!

- Pure canned pumpkin: Use 100% pumpkin puree, not pumpkin pie filling. Pumpkin pie filling already contains sweeteners and spices that would change the recipe.
- Eggs: These help the pumpkin layer set as the cake bakes.
- Evaporated milk: This adds richness to the pumpkin filling.
- Granulated sugar: Sweetens the pumpkin layer.
- Ground cinnamon: Adds warm fall flavor.
- Spice cake mix: Use the dry mix directly from the box. Do not prepare it according to the package directions.
- Unsalted butter: Melt the butter and distribute it as evenly as possible over the dry cake mix.
- Vanilla ice cream and caramel topping: These are optional but especially good with a warm slice.
See recipe card for full information on ingredients and quantities.
Substitutions & Variations
- Cake Mix: Spice cake mix adds extra fall flavor, but you can use yellow or white cake mix for a milder, sweeter topping.
- Pumpkin Pie Spice: If you love warm fall spices, swap the ground cinnamon for pumpkin pie spice for an extra boost of flavor.
- Add Some Crunch: Sprinkle chopped pecans or walnuts over the cake mix before adding the melted butter for a little extra crunch.
- Topping Ideas: Take this pumpkin dump cake to the next level with a scoop of vanilla ice cream, a dollop of whipped cream, or a generous drizzle of caramel sauce. You can even add a sprinkle of cinnamon for extra warmth!
