Pumpkin Dump Cake
I like making pumpkin dump cake because it is simple and forgiving. I usually make it in the fall or when I want a warm baked dessert without much work. The finished cake is soft and moist in the middle with a crumbly, buttery top and bits of crunchy nuts.
Step by Step Method
Prepare the Oven and Pan
I start by heating the oven to 350°F so it is ready when the cake goes in. While the oven heats, I lightly grease a 9×13-inch baking dish. This helps the cake lift out cleanly later and keeps the pumpkin layer from sticking to the bottom.
Make the Pumpkin Base
In a mixing bowl, I stir together the pumpkin puree, granulated sugar, and eggs. I mix until everything looks smooth and thick, with no streaks left behind. The mixture should pour easily but still feel heavy. Once mixed, I spread it evenly into the baking dish, making sure the layer reaches all the corners.
Add the Dry Cake Layer
Next, I sprinkle the dry cake mix evenly over the pumpkin layer. I do not stir or press it down. It should sit loose on top, covering the pumpkin completely. This dry layer is what turns into the crumbly topping during baking.
Finish with Nuts and Butter
I scatter the chopped nuts across the surface so there is crunch in every bite. Then I slice the butter into thin pieces and place them over the top, spacing them as evenly as I can. The butter melts as it bakes and soaks into the cake mix, helping it brown and crisp.
Bake and Cool
I bake the cake uncovered for about 50 minutes. It is done when the top is golden brown and the center looks set, not wet or jiggly. After baking, I let the cake cool for a short time. This helps it firm up so it can be cut into clean squares while still staying soft inside.
Why You Will Love This Recipe
This recipe is easy to put together and does not require careful mixing or special steps. The pumpkin layer stays soft and moist, while the top bakes into a buttery, crumbly crust with crunchy nuts. It tastes rich without being heavy, and it works well served warm or chilled later.

Ingredients
Equipment
Method
- Heat the oven to 350°F. The oven should be fully hot before baking.
- Grease the baking dish lightly so the cake does not stick.
- In a bowl, stir together the pumpkin puree, sugar, and eggs. The mixture should look smooth and thick.
- Spread the pumpkin mixture evenly in the baking dish. It should form a solid orange layer.
- Sprinkle the dry cake mix evenly over the pumpkin layer. Do not mix it in.
- Scatter chopped nuts over the top so they are spread out.
- Cut the butter into thin slices and place them across the top. Try to cover most of the surface.
- Bake uncovered until the top is golden brown and the center looks set, about 50 minutes.
- Let it cool slightly before cutting. The cake should hold together but still feel soft.
Notes
- Do not stir the cake mix into the pumpkin layer, or the texture will turn dense.
- Try to spread the butter evenly so dry spots do not form on top.
- If the top browns too fast, cover it loosely near the end of baking.
- Let the cake cool a bit before cutting, or it may fall apart.
- Macros are approximate and will vary based on ingredient brands and portion size.
Why This Recipe Works
The pumpkin layer stays moist as it bakes, almost like a soft custard. The dry cake mix and butter melt together on top and form a crumbly crust. The nuts add crunch, which balances the soft filling underneath.
Serving Suggestions
I usually serve it warm. A scoop of vanilla ice cream or a swirl of whipped cream on top works well. It also tastes good on its own once it cools.
Fun Fact
Dump cakes get their name because the layers are added straight to the pan without mixing them together.
Conclusion
Pumpkin dump cake is easy to make and keeps well in the fridge for a few days. I reheat leftovers or eat them cold. Sometimes I add more nuts on top if I want extra crunch.
