Save to Pinterest This dump-style pumpkin cake layers creamy spiced pumpkin with dry yellow cake mix, melted butter and chopped pecans for a crunchy top. Whisk pumpkin, sweetened condensed milk, eggs and pumpkin pie spice, spread in a greased 9x13 pan, sprinkle cake mix, drizzle butter, scatter pecans and bake 45–55 minutes at 350°F. Cool at least 30 minutes before serving warm or chilled.
When the days start getting crisp and I spot piles of pumpkins at the market, I get the itch to make something warm and aromatic. One chilly weekend, curiosity nudged me to try out a Pumpkin Dump Cake after a friend described it as the easiest comfort dessert imaginable. I still remember the scent of spiced pumpkin and melting butter curling around the kitchen as it baked. Even on a random Tuesday, baking this brings autumn indoors and makes the house feel instantly warmer.
The first time I made this, it was after a last-minute invitation to an autumn movie night, and I needed something simple but crowd-pleasing. I brought the cake in its pan—still warm—and within minutes everyone was gathering around, drawn by the sweet, spicy aroma. That moment when we spooned out gooey slices together, laughing about how much whipped cream is too much, pretty much made the evening. Since then, I always bake an extra just in case requests for seconds come in strong.
Ingredients
- Pure pumpkin puree (1 can / 425g): Go for pure pumpkin, not pie filling—the flavor is smoother, and you control the sweetness.
- Sweetened condensed milk (1 can / 400g): It binds things together and creates that luscious custard; scrape every last bit from the can.
- Large eggs (3): Crack them in a separate bowl first for shells—easy to beat in and avoid surprises.
- Pumpkin pie spice (1 tablespoon): This instantly brings that classic autumn aroma I crave; adjust to your personal spice comfort.
- Granulated sugar (1/2 cup): A touch of sweetness to enhance the gentle pumpkin; always level off for better accuracy.
- Salt (1/2 teaspoon): Don't skip it—just enough to make the spices sing.
- Yellow cake mix (1 box / about 432g): This is your crust and crumbly topping in one; sprinkle, don't mix in.
- Unsalted butter, melted (1 cup): The butter browns and crisps the topping beautifully; pour slowly to cover as much surface as possible.
- Chopped pecans (1 cup, optional): Toasting beforehand makes an enormous difference and brings out a nutty crunch.
Instructions
- Get Ready to Bake:
- Heat the oven to 350°F (175°C), and lightly grease your trusty 9x13-inch pan so nothing sticks behind.
- Mix Up the Pumpkin Base:
- In a big bowl, whisk pumpkin puree, condensed milk, eggs, pumpkin pie spice, sugar, and salt until smooth—it should smell like pure autumn.
- Layer and Build:
- Pour this custardy mixture into your prepared pan and use a spatula to spread it into the corners for even baking.
- Add Cake Magic:
- Sprinkle the dry yellow cake mix evenly on top—no stirring—just let it float like snow.
- Butter Blanket:
- Slowly drizzle the melted butter right over the cake mix, trying to coat it all; any dry patches create a little extra crunch.
- Nuts for Crunch (Optional):
- Scatter pecans over it all for a toasty, nutty crown, or leave them off if nuts aren't your thing.
- Bake and Wait:
- Bake 45-55 minutes, until the top is golden, with crispy edges and a slight jiggle in the center that will set as it cools.
- Cool and Serve:
- Let the cake cool at least 30 minutes (hardest part) so the layers settle; spoon it up warm or chill for a firmer, sliceable treat.
Save to Pinterest One late October, I made this cake for a neighbor's backyard bonfire instead of the usual apple pie. Standing by the fire, everyone ate off paper plates, and people kept drifting back for just one more scoop with a little melting ice cream. For such a humble tray bake, it sure has a way of bringing people close together.
Making Pumpkin Dump Cake Your Own
I've played around swapping out the pecans for walnuts when that's what I have, and even tried it with coconut sprinkled on top for a fun twist. This cake is so forgiving—a little less sugar, a touch more spice, or a dash of vanilla, and it still tastes amazing. Sometimes, I'll use a mix of brown and white sugar if that's all I can scrape from the canisters. The main thing is to lean into the cozy, warm flavors and have fun with what's already in your pantry.
Troubleshooting the Crispy Topping
Occasionally my cake would have stubborn dry patches on top, but I found that drizzling melted butter carefully and evenly, maybe with a spoon, helps soak the mix better. If a few powdery spots remain, they crisp up nicely instead of staying raw. And don't worry if the topping looks rustic—that crumbly top is exactly what everyone scoops for first. It's a dessert that's meant to be a little perfectly imperfect.
Pumpkin Dump Cake for Every Occasion
Baking this during a rainy weekend always brightens my mood. No special event is needed—I've served it for book club, brought it to a potluck, and made it for Thanksgiving when time was tight.
- Top leftovers with a little maple syrup for breakfast and you won't regret it.
- This cake tastes even better on the second day after a night in the fridge.
- Don't skip the whipped cream—it's not optional in my book.
Save to Pinterest However you serve it, Pumpkin Dump Cake has a way of making simple moments feel generous and special. I hope it brings as much joy to your table as it has to mine.
Common Questions
- → Can I make this dairy-free?
-
Yes. Substitute coconut condensed milk and use a dairy-free cake mix, and replace melted butter with a plant-based spread or melted coconut oil for similar richness.
- → Should I toast the pecans first?
-
Toasting pecans enhances their flavor and crunch. Spread them on a baking sheet and toast at 350°F for 5–8 minutes, watching closely to avoid burning.
- → How do I know when it's done baking?
-
The top should be golden brown and the center set; a toothpick inserted into the center may come out slightly moist but not liquid. The dessert will firm as it cools.
- → Can I use a spice cake mix instead of yellow?
-
Yes. A spice cake mix adds deeper autumnal notes and complements the pumpkin pie spice for a richer, spicier finish.
- → How should leftovers be stored and reheated?
-
Refrigerate leftovers in an airtight container for up to 4 days. Reheat individual portions in a low oven or microwave until warm; serve with whipped cream or vanilla ice cream if desired.
- → Is it possible to freeze this dessert?
-
Yes. Freeze cooled individual portions wrapped tightly in plastic and foil for up to 2 months. Thaw overnight in the fridge and warm gently before serving.
