Pumpkin dump cake is the perfect choice when you want a homemade dessert without rolling pastry, using a mixer, or carefully assembling multiple layers. The pumpkin mixture is whisked in one bowl, and the topping is built directly in the baking dish.
Although the method is wonderfully simple, the texture feels special. The bottom bakes into a smooth, gently spiced pumpkin custard while the cake mix and butter create a golden topping with crisp, crumbly edges.
This dessert is also flexible enough for casual family dinners, Thanksgiving gatherings, fall potlucks, and holiday brunches. It tastes inviting straight from the oven, but it can also be chilled and served in neat squares the next day.

Ingredients You’ll Need
The ingredient list is short, familiar, and easy to find. For the best results, use plain pumpkin purée rather than a can labeled pumpkin pie filling, since pie filling already contains sugar and spices.
- Pumpkin purée: One 15-ounce can provides the creamy base and rich autumn color.
- Evaporated milk: This gives the pumpkin layer a smooth, custardy consistency without adding excess water.
- Eggs: Three large eggs help the pumpkin layer set while keeping it tender.
- Sugar, cinnamon, and salt: These balance the pumpkin flavor and bring out its natural sweetness.
- Yellow cake mix: A standard 15.25-ounce box works well, although some brands are closer to 18.25 ounces.
- Melted butter: One cup, or two sticks, moistens the cake mix and creates the rich golden topping.
- Pecans or walnuts: These are optional, but add crunch and a pleasant roasted flavor.
Salted or unsalted butter may be used. If you choose salted butter, you can omit the added salt, though the listed teaspoon gives the pumpkin layer a nicely balanced flavor when using unsalted butter.
For a more pronounced spice profile, replace the one teaspoon of cinnamon with about two teaspoons of pumpkin pie spice. Fans of creamy pumpkin desserts can also try this pumpkin cream cheese cake when they want a ring-shaped centerpiece.
How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C). Grease a 9-by-13-inch baking dish with butter or nonstick cooking spray, paying attention to the corners so the finished cake is easy to serve. Set the dish aside while you prepare the pumpkin layer.
Step 2: Add the pumpkin purée, evaporated milk, three large eggs, granulated sugar, cinnamon, and salt to a large mixing bowl. Whisk until the mixture looks smooth and evenly blended, with no visible streaks of egg or pockets of dry sugar.
Step 3: Pour the pumpkin mixture into the greased baking dish. Gently tilt the dish or use a spatula to spread it into an even layer, which helps the cake bake at the same rate from edge to center.
Step 4: Sprinkle the dry yellow cake mix evenly over the entire pumpkin surface. Do not stir the cake mix into the pumpkin layer, because the separate layers are what create the signature custard-and-cake texture.
Step 5: Drizzle the melted butter over the cake mix as evenly as possible. Work slowly across the dish and look for uncovered patches, since dry areas of cake mix may remain powdery after baking; scatter the optional chopped pecans or walnuts over the buttered surface.
Step 6: Bake for 50 to 60 minutes, checking near the shorter end of the baking range. The top should be golden brown, and the center should be mostly set but still have a slight soft, custard-like movement when the dish is gently nudged.
Step 7: Let the cake rest for about 15 to 20 minutes before cutting. This brief cooling time allows the pumpkin layer to firm while keeping its soft texture, making the servings easier to lift from the dish.
Pro Tips for the Best Pumpkin Dump Cake
Even butter coverage is the most important detail in this recipe. Pouring it slowly in thin streams helps moisten more of the cake mix, while a pastry brush or the back of a spoon can help guide butter toward small dry spots.
Do not be tempted to stir after sprinkling on the cake mix. Stirring changes the layers and can make the topping less distinct, while leaving everything undisturbed allows the pumpkin mixture to rise gently through the cake mix as it bakes.
Keep an eye on the center during the final minutes. A slight wobble is desirable because the pumpkin layer continues to set as it rests, but the top should be browned and the edges should look baked rather than wet.
Package sizes vary between brands, so a 15.25-ounce box and an older-style 18.25-ounce box may both be used. The topping may be a little thicker or thinner depending on the box size, but both versions work well in a 9-by-13-inch dish.

Serving Ideas
Let the cake cool briefly, then spoon it onto plates while it is still warm. The soft pumpkin center pairs beautifully with a cool, airy topping, so add a generous dollop of whipped cream or a scoop of vanilla ice cream.
A light sprinkle of cinnamon makes each serving look inviting without adding extra sweetness. You can also add a few toasted pecans, although the optional nuts already provide plenty of crunch throughout the topping.
For a dinner party, bake the cake earlier in the day and let it rest before covering it. Serve portions slightly warm, at room temperature, or chilled according to your preference.

Storage and Reheating
Because the pumpkin layer is custard-like, refrigerate leftovers once the cake has cooled. Cover the baking dish or transfer servings to an airtight container, and enjoy them chilled or gently warmed.
To reheat an individual portion, place it in the microwave and warm it in short intervals until comfortable to eat. Avoid overheating, since too much heat can make the pumpkin layer lose its tender texture.
The cake is especially good the day after baking, when the flavors have had time to settle and the pumpkin layer has firmed slightly. Add whipped cream or ice cream just before serving rather than storing it on top.
Easy Variations
Use pecans for a classic Southern-style flavor or walnuts for a slightly earthier bite. You may also leave the nuts out entirely for a smooth, family-friendly topping that still has plenty of buttery crunch from the cake mix.
For extra spice, use about two teaspoons of pumpkin pie spice in place of the cinnamon. When using salted butter, omitting the additional salt is an option, particularly if you prefer a sweeter-tasting pumpkin layer.
This recipe is also a welcoming addition to a holiday dessert spread alongside a more decorative cake. For a celebration with a rich, colorful center, consider serving it with this festive Christmas cake.
