This pumpkin dump cake brings together a creamy pumpkin pie filling and a golden, buttery yellow cake mix topping. It is a cozy dessert for Thanksgiving, a fall potluck, or a quiet weekend at home, and you do not need a mixer or a pie crust. A little whisking, a few easy layers, and the oven takes care of the rest.
If you are new to dump cakes, here is the most helpful thing to know: this is a scoopable dessert with a soft pumpkin base, not a fluffy layer cake. Let it rest after baking so each spoonful holds together beneath that crumbly topping.

Ingredients
For the pumpkin filling
- 1 can (15 ounces) pure pumpkin puree, not pumpkin pie filling
- 1 can (12 fluid ounces) evaporated milk, not sweetened condensed milk
- 3 large eggs
- 3/4 cup granulated sugar
- 2 teaspoons pumpkin pie spice
- 1 teaspoon vanilla extract
- 1/2 teaspoon fine salt
For the yellow cake mix topping
- 1 box (15.25 ounces) yellow cake mix, dry and unprepared
- 1 cup (2 sticks or 8 ounces) unsalted butter, melted
- 1/2 cup chopped pecans, optional
- Whipped cream or vanilla ice cream, optional for serving
Check the box size: this recipe is written for 15.25 ounces of cake mix. If your box is smaller, weigh out additional dry yellow cake mix from a second box to reach 15.25 ounces. Do not add the eggs, oil, or water listed on the cake mix package.
No pumpkin pie spice? Use 1 teaspoon ground cinnamon, 1/2 teaspoon ground ginger, 1/4 teaspoon ground nutmeg, and 1/4 teaspoon ground cloves instead. Use plain canned pumpkin for a consistent filling; watery homemade puree can make the center slow to set.
How to Make Pumpkin Dump Cake with Yellow Cake Mix
1. Prepare the oven and baking dish
Heat the oven to 350°F with a rack in the center. Lightly grease a 9×13-inch baking dish that is at least 2 inches deep. Set it on a rimmed baking sheet if you want easier handling. Melt the butter and set it aside while you mix the filling.
2. Whisk the pumpkin filling
In a large bowl, whisk the eggs until the whites and yolks are blended. Add the pumpkin puree, evaporated milk, sugar, pumpkin pie spice, vanilla, and salt. Whisk until smooth, scraping the bottom of the bowl so no streaks of pumpkin remain. Pour into the prepared dish and spread evenly.
3. Add the dry cake mix
Sprinkle the dry yellow cake mix evenly over the pumpkin mixture, working all the way to the corners. Break up any large lumps with your fingers before sprinkling. Keep the cake mix on top: do not stir it into the pumpkin filling.
4. Cover the topping with butter
Slowly drizzle the melted butter over the entire surface in thin passes. Use the back of a spoon to gently spread butter over any large dry patches without mixing the layers together. Sprinkle with the chopped pecans, if using. Even butter coverage helps the cake mix bake into a golden topping instead of leaving pockets of powder.
5. Bake until the filling sets
Bake for 50 to 60 minutes, beginning your checks at 45 minutes because ovens and baking dishes vary. The topping should be golden, the edges set, and the center should have a slight jiggle rather than a liquid slosh when you gently nudge the dish. If the top browns before the center sets, loosely tent it with foil and continue baking in 5-minute increments. An instant-read thermometer inserted into the pumpkin layer at the center should reach at least 160°F; also check the texture, since temperature alone does not tell you whether the filling has fully set.
6. Rest and serve
Place the dish on a heatproof rack and let it rest for about 30 minutes. The pumpkin layer firms as it cools, so resist scooping straight from the oven. Serve warm in bowls with whipped cream or a small scoop of vanilla ice cream. For firmer portions, refrigerate the cooled cake and serve chilled.
Tips for Success and Easy Variations
- Keep the layers separate: mix the pumpkin filling thoroughly, then leave the dry cake mix and butter on top.
- Skip the nuts: pecans are optional and do not change the basic baking method.
- Try spice cake mix: use the same 15.25-ounce weight and reduce the pumpkin pie spice in the filling to 1 teaspoon if you prefer a gentler spice flavor.
- Add caramel at serving time: a light drizzle on individual portions adds sweetness without changing how the cake bakes.

Troubleshooting
Why is there dry cake mix on top?
The butter probably did not reach every patch, or the mix was piled too thickly in one spot. Before baking, spread it into an even layer. If you notice small powdery areas during baking, carefully spoon a little melted butter directly over those spots and continue baking until they are moistened and cooked. Do not stir the hot layers together.
Why is the pumpkin filling runny?
A small wobble while hot is normal, but a sloshing center needs more time. Cover a browned top loosely with foil and continue baking. Also check that you used a 15-ounce can of pumpkin, a 12-fluid-ounce can of evaporated milk, and the specified pan. A smaller, deeper pan or watery puree can delay setting. Give the cake its cooling time before judging the final texture.
Why is the topping getting too dark?
The oven may run hot, the dish may be too close to the upper heating element, or the pecans may be browning first. Move the dish to the center rack if needed and tent loosely with foil. Keep baking until the pumpkin layer is done.
Why does it not slice like a regular cake?
That is the expected texture. Pumpkin dump cake has a custard-like base and a crumbly topping, so warm servings are best scooped. Chilling makes it easier to portion, but it will still be softer than a layer cake.
How to Store and Reheat
Because this dessert contains an egg-and-milk filling, refrigerate leftovers in a covered container within 2 hours of baking. Use shallow containers for smaller portions so they cool more quickly. Keep refrigerated for up to 3 to 4 days. This follows USDA guidance for baked egg dishes.
Reheat an individual serving in the microwave in short bursts until the center reaches 165°F. For several portions, place them in an oven-safe dish, cover loosely, and warm at 300°F. The topping will soften in storage; uncover briefly near the end of oven reheating if you want a drier top.
To freeze, portion the cooled cake into airtight freezer-safe containers and freeze for up to 2 months for best quality. Thaw overnight in the refrigerator before reheating. Expect the topping to be softer after thawing.
Frequently Asked Questions
Do I prepare the yellow cake mix first?
No. Sprinkle it on dry, straight from the box. The eggs and evaporated milk in the ingredient list belong in the pumpkin filling, and the melted butter goes over the dry cake mix. Ignore the package directions for making a regular cake.
Can I use pumpkin pie filling instead of pumpkin puree?
Use plain pumpkin puree for this recipe. Pumpkin pie filling already contains sugar and spices, so substituting it directly changes both the sweetness and seasoning.
Can I use sweetened condensed milk?
Not as a direct substitute. Sweetened condensed milk is much sweeter and thicker than evaporated milk. Choose the can labeled evaporated milk to keep the recipe proportions consistent.
Can I make pumpkin dump cake ahead of time?
Yes. Bake it a day ahead, refrigerate it within 2 hours, and keep it covered. Serve chilled or reheat before serving. For the crispest topping, bake it on the day you plan to serve it. Avoid assembling the dry topping long before baking because it can absorb moisture unevenly.
Can I leave out the eggs?
The eggs help the pumpkin layer set, so simply leaving them out can produce a loose filling. This version is written for three large eggs; choose a recipe developed without eggs if you need that substitution.
Can I use homemade yellow cake batter?
Prepared cake batter is not a direct replacement for dry boxed mix in this layered recipe. If you are in the mood for a scratch-made cake instead, my Best Yellow Cake Recipe: Moist and Buttery is a separate baking project to explore.
