Pumpkin dump cake is the dessert that broke the internet: you layer everything in the pan, you do not stir a single thing, and an hour later you pull out a warm, gooey pumpkin base under a golden, buttery, crisp topping. Five versions follow below.
Why You’ll Love This Pumpkin Dump Cake
No creaming butter, no rolling dough, no mixer to wash. You whisk the pumpkin layer, sprinkle the dry cake mix on top, drizzle melted butter over it, and the oven does the rest. The bottom stays soft and custardy like the center of a pumpkin pie, while the top bakes into a crackly, buttery crumble. It is nearly impossible to ruin — the moist pumpkin layer forgives an extra five minutes, and dry topping patches can be fixed with extra butter. One pan feeds a crowd.
Ingredients You’ll Need
Base recipe: one 9×13-inch pan, about 12 servings.
- 1 can (15 oz) pumpkin puree — not pie filling, which is already sweetened and spiced
- 1 can (12 oz) evaporated milk
- 3 large eggs, at room temperature
- 1 cup granulated sugar
- 1 teaspoon vanilla extract
- 2 teaspoons pumpkin pie spice, plus 1/2 teaspoon cinnamon
- 1/2 teaspoon salt
- 1 box (15.25 oz) yellow cake mix
- 3/4 cup (12 tablespoons) unsalted butter, melted
- 1 cup chopped pecans, optional
- Vanilla ice cream, for serving
How to Make Pumpkin Dump Cake
Heat the oven to 350°F and grease a 9×13-inch baking dish. Whisk the pumpkin puree, evaporated milk, eggs, sugar, vanilla, pumpkin pie spice, cinnamon, and salt until smooth, about 1 minute. Pour into the dish and spread into an even layer. Sprinkle the dry cake mix evenly over the top, breaking up lumps with your fingers, and do not stir. Drizzle the melted butter evenly across the surface, then scatter the nuts on top. Bake 50 to 55 minutes, until the edges are set and bubbling, the center barely jiggles, and the topping is deep golden brown. Rest at least 20 minutes before scooping so the pumpkin layer firms up.
1. Classic Pumpkin Dump Cake (the viral “don’t stir” method)
This is the version that went viral, and the no-stir rule is the whole trick. Leaving the cake mix dry lets the butter soak into some spots and leave others crisp, for a cobbler-like topping instead of a uniform cake layer. Bake at 350°F for 50 to 55 minutes. Stirring the mix into the pumpkin is the classic mistake — it gives you a dense, gummy sponge instead of two distinct layers. Serve warm with vanilla ice cream.
2. Pumpkin Spice Dump Cake with pecans
Add 1 extra teaspoon of pumpkin pie spice and 1/2 teaspoon of ground ginger to the pumpkin layer for sharper warm spice. Swap in a spice cake mix for a deeper flavor. Scatter 1 cup of chopped pecans over the top and press them lightly into the cake mix so they toast instead of sliding off. Bake at 350°F for 50 to 55 minutes; the nuts should look glossy and toasted, not dark. Finish with a drizzle of caramel sauce.
3. Pumpkin Dump Cake with Cream Cheese Swirl
Beat 8 oz of softened cream cheese with 1/4 cup of sugar and 1 egg yolk until smooth. Drop spoonfuls over the pumpkin layer and drag a knife through once or twice for loose ribbons — do not over-swirl or the cream cheese disappears. Add the cake mix and butter as usual. Bake at 350°F for 55 to 60 minutes; the extra moisture needs the additional five minutes, and the center should be set with only the faintest jiggle. Chill 1 hour before cutting for neat squares.
4. Slow Cooker Pumpkin Dump Cake
Grease a 6-quart slow cooker and pour in the pumpkin layer. Sprinkle the cake mix over the top, drizzle with the melted butter, and add the nuts. Lay a clean kitchen towel across the top before putting the lid on — it catches condensation so it does not drip onto the topping and make it soggy. Cook on high for 2 to 2 1/2 hours or on low for 4 to 4 1/2 hours, until the edges are set and the center is just barely jiggly. The topping stays softer than the oven version, so serve it in bowls with a spoon.
5. Pumpkin Chocolate Chip Dump Cake
Use a chocolate cake mix instead of yellow, and fold 1 cup of semi-sweet chocolate chips into the pumpkin layer before pouring it in. The chips melt into pockets that stay soft even after the cake cools. Sprinkle another 1/2 cup of chips over the cake mix before drizzling the butter — they melt into the topping and give it dark, glossy streaks. Bake at 350°F for 50 to 55 minutes. Chocolate masks browning, so judge doneness by the edges: set and pulling slightly away from the pan, with the center jiggling only a little. Serve warm, while the chocolate is still molten.
Tips for the Best Pumpkin Dump Cake Every Time
Butter coverage decides whether the topping turns crisp or dusty. Melted butter is the only moisture the dry cake mix gets, so drizzle slowly and tilt the pan to fill gaps. Pale, powdery patches after baking mean the butter missed those spots — spoon butter over them next time, or melt an extra 2 tablespoons. Use room-temperature eggs and real pumpkin puree, not pie filling, or the sweetness and spice will be off. Rest the cake at least 20 minutes after baking; cutting into it hot gives you soup. If your oven runs hot, check at 45 minutes and tent loosely with foil if the top browns too fast.
Easy Variations
Swap the yellow cake mix for white cake mix for a lighter topping, or use a butter pecan cake mix for a nuttier flavor. Stir 1/2 cup of toffee bits into the topping for extra crunch. For a gluten-free version, use a gluten-free yellow cake mix and check that your spice blend is certified gluten-free. Make it dairy-free with melted coconut oil instead of butter and a dairy-free cake mix. For individual servings, divide between eight greased ramekins and bake at 350°F for 30 to 35 minutes.
Storage and Reheating
Cool completely, then cover the pan tightly with plastic wrap or transfer slices to an airtight container. It keeps in the refrigerator for up to 5 days, and tastes better on day two. To reheat, microwave a single serving for 30 to 45 seconds, or warm the whole pan in a 300°F oven for 15 minutes, covered loosely with foil. Freeze individual portions wrapped in plastic wrap inside a freezer bag for up to 3 months; thaw overnight in the refrigerator and reheat as above. Do not freeze the cream cheese swirl version for more than 1 month — the cream cheese can turn grainy. Never leave it at room temperature for more than 2 hours.
Frequently Asked Questions
Why shouldn’t I stir a dump cake? Stirring mixes the dry cake mix into the wet pumpkin layer, and you lose the two textures that make it work — the custardy bottom and the crisp topping.
Why are there dry spots on top of my cake? Dry, powdery patches mean the melted butter did not reach those areas. Next time, drizzle more slowly and evenly, or spoon butter over bare spots before baking. You can also drizzle 2 extra tablespoons of melted butter over the finished cake while it is hot.
Can I use fresh pumpkin instead of canned? Yes, but roast and puree it first, then drain it well — fresh pumpkin holds much more water than canned, and excess moisture makes the bottom soggy. You need 1 3/4 cups of thick, well-drained puree per 15 oz can.
Can I make pumpkin dump cake ahead of time? Yes. Bake it the day before, cool, cover, and refrigerate. The topping softens overnight, so reheat uncovered in a 325°F oven for 15 to 20 minutes to crisp it back up.
Is pumpkin dump cake the same as pumpkin pie? Not quite. Same spiced pumpkin flavor, different texture — a soft, spoonable pumpkin layer under a crumbly cake topping instead of a pastry crust.
Nutrition Estimate
These values are an estimate only, based on the classic version cut into 12 servings. Actual numbers will vary by cake mix brand, butter amount, and toppings. One serving has roughly 340 calories, 16 grams of fat, 46 grams of carbohydrates, 2 grams of fiber, 29 grams of sugar, and 4 grams of protein. The pumpkin adds vitamin A and fiber, but the sugar and butter are doing the heavy lifting.
The Bottom Line
Pumpkin dump cake earns its viral reputation because it delivers a real, from-scratch-tasting dessert with ten minutes of work and one pan to wash. Start with the classic, then branch into the pecan, cream cheese, slow cooker, or chocolate chip version once you know what your crowd loves. Make it the day before a gathering, reheat to crisp the topping, and serve warm with ice cream.
