This pumpkin dump cake is the easiest fall dessert: a warmly spiced pumpkin layer that bakes into a smooth, custard-like base similar to pumpkin pie, topped with a buttery cake crust that turns golden and slightly crisp.
This version leans into the classic pumpkin crunch style, with a creamy bottom and a perfectly textured topping made from dry cake mix, pecans, and melted butter. It’s quick to assemble, dependable, and always a crowd-pleaser for potlucks, holidays, or cozy family dinners.

What Is Pumpkin Dump Cake?
Pumpkin dump cake is a layered, no-fuss dessert made by pouring a spiced pumpkin mixture into a baking dish, sprinkling dry cake mix on top, and covering it with butter and optional nuts. During baking the bottom becomes soft and custardy while the top forms a rich, golden crust.
Despite the name, it’s not a traditional light, fluffy cake. The texture is closer to a cobbler or crisp: a silky pumpkin base with a buttery, slightly crisp topping.
No batter mixing is required. The layers bake separately, creating the contrast between the smooth pumpkin filling and the cakey, crunchy top that makes dump cakes so irresistible.
What This Pumpkin Dump Cake Tastes Like
This dessert delivers warm, cozy fall flavors. The pumpkin layer is silky and custard-like, similar to pumpkin pie filling, while the topping bakes into a buttery, golden crust with slightly crisp edges. Between those layers you’ll find a softer cake-like middle that brings everything together.
It’s not light or airy; instead it’s a satisfying cross between pumpkin pie and a crisp, with familiar spices and a rich finish in every bite.
Before You Begin
Use pure pumpkin, not pumpkin pie filling: Pumpkin pie filling is pre-sweetened and spiced and will change the recipe’s flavor and texture. Use 100% pumpkin puree.
Don’t mix the layers: Resist stirring after adding the cake mix. The separate layers are what create the classic dump cake texture.
Distribute the butter evenly: Make sure the butter covers as much of the dry cake mix as possible to avoid dry, powdery spots.
Expect a custard-style base: The bottom will bake to a soft, sliceable custard—this is normal and desirable.
The center should slightly jiggle: Like pumpkin pie, the center may be a little jiggly when you remove it; it will firm up as it cools.
Let it cool before serving: Cooling helps the layers set so you can slice or scoop clean portions.

Pumpkin Dump Cake Ingredients + Key Notes
Below are the essential ingredients and what they do; see the recipe card for exact measurements.
- Pumpkin puree: Use 100% pumpkin puree — not pre-spiced pumpkin pie filling.
- Evaporated milk: Adds the rich, smooth texture that makes the filling custardy.
- Eggs: Help the pumpkin layer set so it slices neatly.
- Sugar + pumpkin pie spice: Provide classic warm, autumnal flavors.
- Yellow cake mix: Creates the buttery, cakey topping; vanilla or spice cake mixes also work.
- Butter: Melts into the dry cake mix to form the golden crust—distribute evenly.
- Pecans: Optional but recommended for a crunchy, nutty topping.
Tip: After sprinkling the dry cake mix, gently press it down slightly to improve contact with the pumpkin layer so it bakes more evenly.
How to Make Pumpkin Dump Cake

- Make the pumpkin layer: Whisk pumpkin puree, evaporated milk, eggs, sugar, pumpkin pie spice, and a pinch of salt until smooth. Pour into a greased 9 x 13-inch baking dish.
- Add the cake mix: Sprinkle the dry cake mix evenly over the pumpkin. Do not stir.
- Press and add pecans: Gently press the dry mix down, then scatter chopped pecans on top if using.
- Add the butter: Drizzle melted butter evenly across the surface or place very thin slices of butter to cover the dry mix.
- Bake: Bake until the top is golden and the edges are set, with a slight jiggle in the center, similar to pumpkin pie.
- Cool: Let the dessert cool for 20–30 minutes before serving so the pumpkin layer can firm up.
Pumpkin Dump Cake Variations
You can easily adapt this recipe to your taste:
- Pumpkin Crunch Dump Cake: The classic—add pecans for a crunchy top.
- Pumpkin Pecan Dump Cake: Increase the pecans or add a variety of nuts for extra texture.
- Pumpkin Pie Dump Cake: Omit the nuts for a softer, pie-like finish.
- Cake mix choices: Yellow or vanilla cake mix are great; spice cake mix intensifies fall flavors.
Pro Tips
- Use thin butter slices or drizzle melted butter for even coverage.
- Rotate the pan halfway through baking for uniform browning.
- Check edges for doneness: they should be set and pulling slightly from the pan.
- Let the cake rest before serving so the custard layer firms up.
- Serve slightly warm for the best contrast of crisp topping and creamy filling.
What to Serve With Pumpkin Dump Cake
Cold, creamy toppings balance the rich, spiced base—serve with vanilla ice cream or whipped cream. Pair with hot coffee, hot chocolate, or a spiced latte for a cozy fall treat.
Storing, Freezing, and Make-Ahead
Refrigerator: Cover loosely with foil or plastic wrap. Keeps 3–4 days.
Freezing: Cool completely, wrap tightly in plastic wrap and foil, and freeze up to 2–3 months (best within 2 months). Thaw slowly in the refrigerator and reheat gently before serving.
Make-ahead: With only about 10 minutes active prep, it’s easy to assemble a day ahead and bake the next day, or bake in advance and refrigerate.

Frequently Asked Questions
Why is my pumpkin dump cake runny?
It likely needs more time in the oven. The center should be mostly set with a slight jiggle; it will finish setting as it cools.
Why is my topping dry or powdery?
The butter didn’t sufficiently cover the cake mix. Make sure the butter is distributed evenly so the topping bakes golden.
Can I use pumpkin pie filling?
No. Pumpkin pie filling is sweetened and spiced and will change the flavor and texture. Use plain pumpkin puree.
Can you freeze pumpkin dump cake?
Yes. Cool completely, wrap tightly, and freeze for up to 2–3 months. Thaw in the fridge and reheat before serving.
Do I have to use pecans?
No. Pecans are optional but add a lovely crunch that complements the creamy pumpkin base.
