Pumpkin Dump cake Recipe tastes like a cross between pumpkin pie and buttery crumb cake with crunchy pecan bits on top. It works perfectly for busy home cooks who want a cozy fall dessert on the table in about 1 hour with only 10 to 15 minutes of hands-on time. I baked my first version of this on a tiny apartment oven rack that tilted to one side, so trust me, this recipe forgives a lot.
Why Make This Pumpkin Dump cake Recipe at Home
You mix everything in the baking dish, so you skip extra bowls and a sink full of dishes. The recipe uses pantry staples like canned pumpkin, boxed cake mix, and evaporated milk, so you can keep everything on hand and bake whenever a pumpkin craving hits.
You control the sweetness, spice level, and crunch, which beats a store-bought dessert that tastes the same every time. The cake tastes even better the next day, so you can bake it ahead for holidays, potlucks, or a random Tuesday night pumpkin fix.
This Pumpkin Dump cake Recipe tastes like pumpkin pie with a buttery crunchy topping, and my whole family scraped the pan clean. ★★★★★
Ingredients You Need
Pumpkin layer
- 1 can (15 ounces) pure pumpkin puree
- Use 100% pumpkin, not pumpkin pie filling. Libby’s or store brand both work well.
- 1 can (12 ounces) evaporated milk
- Evaporated milk gives a custardy texture. Use full fat for best flavor.
- 3 large eggs
- Room temperature eggs mix more smoothly, but cold eggs still work.
- 3/4 cup granulated sugar
- 1/4 cup light brown sugar, packed
- Brown sugar adds caramel notes and extra moisture.
- 2 teaspoons pumpkin pie spice
- Or use 1 1/2 teaspoons cinnamon, 1/4 teaspoon nutmeg, 1/4 teaspoon ginger, and a pinch of cloves.
- 1 teaspoon pure vanilla extract
- 1/2 teaspoon fine sea salt
Cake topping
- 1 box yellow cake mix (about 15.25 ounces)
- Yellow cake mix gives a rich flavor, but you can use spice cake mix for extra warmth or white cake mix for a milder taste.
- 3/4 cup unsalted butter, melted and slightly cooled
- Use real butter, not margarine, for best flavor. Salted butter works too; just reduce added salt a bit.
Optional crunch and add-ins
- 3/4 cup chopped pecans or walnuts
- Toast them in a dry skillet for a few minutes to deepen the flavor.
- 1/3 cup toffee bits or mini chocolate chips
- Sprinkle over the pumpkin layer before the cake mix if you want extra sweetness.
Pantry shortcuts and substitutions
- Use canned pumpkin puree, not fresh, if you want consistent texture and less prep.
- Swap evaporated milk with half-and-half in a pinch, but avoid regular milk because it makes the custard looser.
- Use a gluten free yellow cake mix to turn this into a gluten free pumpkin dump cake.
- Reduce sugar slightly if you use a very sweet cake mix or add chocolate chips.
Equipment list
- 9×13 inch baking dish (glass or metal)
- Large mixing bowl (optional, you can mix directly in the baking dish if you prefer)
- Whisk and rubber spatula
- Measuring cups and spoons
- Small bowl or measuring cup for melting butter
- Oven mitts and a wire rack for cooling
Tips & Mistakes
- Grease the baking dish lightly so slices come out clean and the corners do not stick.
- Whisk the pumpkin mixture until smooth so the custard bakes evenly without streaks of egg.
- Spread the dry cake mix in an even layer and break up clumps so you avoid dry flour pockets.
- Drizzle the melted butter evenly over the cake mix and cover as much surface as possible to help everything brown.
- Do not stir after you add the cake mix and butter, or you will lose the layered texture.
- Bake until the center barely jiggles and the top looks golden and crisp, since underbaking keeps the middle too soupy.
- Let the pumpkin dump cake cool at least 20 to 30 minutes so the custard sets and slices hold their shape.
- Use a metal pan if you want a slightly crisper top and a glass pan if you prefer a softer texture.
- Tent the pan loosely with foil if the top browns too quickly before the center finishes baking.
- Chill leftovers promptly so the custard stays safe and the flavors continue to develop.
How to Make Pumpkin Dump cake Recipe
Step 1: Preheat and prep the pan
Preheat your oven to 350°F. Lightly grease a 9×13 inch baking dish with butter or nonstick spray. Set the dish aside while you mix the pumpkin layer.
Step 2: Mix the pumpkin custard base
In a large bowl, whisk together pumpkin puree, evaporated milk, eggs, granulated sugar, brown sugar, pumpkin pie spice, vanilla, and salt. Whisk until the mixture looks smooth and well combined with no streaks of egg. Pour the pumpkin mixture into the prepared baking dish and spread it into an even layer.
Step 3: Add optional add-ins
If you use toffee bits, chocolate chips, or nuts inside the cake, sprinkle them evenly over the pumpkin layer now. Keep some nuts for the top if you want extra crunch. Gently tap the pan on the counter to settle everything.
Step 4: Add the dry cake mix
Open the box of yellow cake mix and sprinkle the dry mix evenly over the pumpkin layer. Use your hand or a spoon to spread it out and cover the pumpkin completely. Break up any visible clumps so the topping bakes evenly.
Step 5: Add butter and nuts
Pour the melted butter slowly over the entire surface of the cake mix. Aim to cover as much of the dry mix as you can with the butter so the topping browns and crisps. Sprinkle chopped pecans or walnuts over the top if you want a crunchy finish.
Step 6: Bake
Place the baking dish on the center rack of the oven. Bake for 45 to 55 minutes, until the top looks golden brown and the edges bubble slightly. Check the center by giving the pan a gentle shake; it should jiggle a little like pumpkin pie but not slosh.
Step 7: Cool and set
Remove the pumpkin dump cake from the oven and place it on a wire rack. Let it cool at least 20 to 30 minutes so the custard layer sets and the slices hold together. Serve warm, at room temperature, or chilled, depending on your preference.
Variations I've Tried
I swap yellow cake mix with spice cake mix when I want extra cinnamon and warm spices. I use chocolate cake mix and mini chocolate chips when I crave a richer, almost brownie-like pumpkin dessert. I add a layer of thinly sliced apples over the pumpkin mixture before the cake mix for a pumpkin apple dump cake twist.
I stir a handful of shredded coconut into the cake mix for a toasty, chewy top. I use a mix of pecans and walnuts when I want more texture and flavor. I drizzle caramel sauce over each serving and top with chopped pecans for a pumpkin caramel dump cake vibe.
How to Serve Pumpkin Dump cake Recipe
Serve Pumpkin Dump cake Recipe warm with a big scoop of vanilla ice cream so the ice cream melts into the crunchy topping. Add a dollop of whipped cream and a light dusting of cinnamon for a bakery-style finish. Pair slices with hot coffee, chai, or cold milk for a cozy dessert or afternoon snack.
You can serve it straight from the pan for casual family dinners or spoon it into pretty bowls for holidays. The texture sits somewhere between cake and pudding, so it works well as a spoon dessert too.
How to store
- Cool the pumpkin dump cake completely, then cover the pan tightly or transfer slices to airtight containers.
- Store in the fridge for up to 4 days; the flavors deepen and the texture stays moist.
- Freeze individual slices or the whole pan (well wrapped) for up to 2 months.
- Thaw overnight in the fridge, then reheat portions in the microwave for 20 to 30 seconds or in a 300°F oven for 10 to 15 minutes until warm and slightly crisp on top.
