What Is Pumpkin Dump Cake?

Pumpkin dump cake is an easy layered dessert made by pouring a spiced pumpkin mixture into a baking dish and topping it with dry cake mix and butter. As it bakes, the bottom becomes soft and custardy—similar to pumpkin pie—while the top turns into a buttery, golden crust.

Despite the name, this isn’t a traditional cake with a light, fluffy texture. It’s much closer to a crisp or cobbler, with a creamy base and a rich, slightly crisp topping.

There’s no mixing or batter involved. The layers stay separate as they bake, creating that signature contrast between smooth and buttery textures that makes dump cakes so irresistible.

What This Pumpkin Dump Cake Tastes Like

This dessert has a rich, cozy flavor and a texture that’s very different from a traditional cake.

The bottom layer is smooth, creamy, and softly set—very similar to pumpkin pie filling. The top bakes into a buttery, golden layer that’s slightly crisp around the edges. In between, you’ll get a softer cake layer that ties everything together.

It’s not light or fluffy like a classic cake. Instead, it’s more like a cross between a pumpkin pie and a crisp or cobbler, with warm spices and a rich, buttery finish in every bite.

✨ Before You Begin

✨ Use pure pumpkin, not pumpkin pie filling: Pumpkin pie filling is already sweetened and spiced, which can throw off both the flavor and texture. Stick with 100% pumpkin puree for the best results.

✨ Don’t mix the layers: It may feel strange, but resist the urge to stir. Dump cakes work because the layers stay separate, creating that creamy base and buttery topping.

✨ Distribute the butter evenly: This is the key to a perfect topping. Make sure the butter covers as much of the dry cake mix as possible so you don’t end up with dry, powdery spots.

✨ Expect a custard-style base: The bottom layer will bake up soft and creamy, similar to pumpkin pie. This is not a fluffy cake—and that’s exactly what you want.

✨ The center should slightly jiggle: Just like pumpkin pie, the center may still have a slight jiggle when you pull it from the oven. It will continue to set as it cools.

✨ Let it cool before serving: This helps the layers set properly and makes it easier to scoop or slice without falling apart.

Pumpkin Dump Cake Ingredients + Key Notes

This is just a quick glance at what you’ll need. For exact measurements and the full ingredient list, head down to the recipe card below.

Pumpkin puree: Be sure to use 100% pure pumpkin puree, not pumpkin pie filling. Pumpkin pie filling is already sweetened and spiced, which can throw off both the flavor and the texture of your pumpkin dump cake.

Evaporated milk: This gives the pumpkin layer its rich, smooth, pumpkin-pie-style texture. It helps create that soft custardy base that makes this dessert so good.

Eggs: The eggs help the pumpkin layer set as it bakes. That’s why the bottom of this dessert is creamy and sliceable instead of loose.

Sugar + pumpkin pie spice: These give the filling its classic warm fall flavor. The sugar sweetens the pumpkin base, while the spice brings that familiar pumpkin pie taste.

Yellow cake mix: Yellow cake mix gives the topping a buttery, classic dump cake flavor that pairs beautifully with pumpkin. Vanilla cake mix also works well if that’s what you have on hand.

Butter: The butter is what transforms the dry cake mix into that rich, golden topping. Try to distribute it as evenly as possible so you don’t end up with dry, powdery patches.

Pecans: Pecans are optional, but they add the classic crunch that makes this feel like a true pumpkin crunch dump cake. They also bring a rich, nutty flavor that works really well with the soft pumpkin base.

Gently press the cake mix: After sprinkling the dry cake mix over the pumpkin layer, gently press it down before adding the pecans and butter. This helps the topping make better contact with the filling so it bakes more evenly.

How to tell when it’s done: Don’t test this like a traditional fluffy cake. You’re looking for a golden topping, set edges, and a center that is mostly set with just a slight jiggle, similar to pumpkin pie.

🥣 How to Make Pumpkin Dump Cake

Make the pumpkin layer: In a large mixing bowl, whisk together the pumpkin puree, evaporated milk, eggs, sugar, and pumpkin pie spice until smooth and well combined. Pour the mixture evenly into a greased baking dish.

Add the cake mix: Sprinkle the dry cake mix evenly over the pumpkin layer. Do not stir—this is what creates the distinct layers as it bakes.

Press and top: Gently press the cake mix down into the pumpkin layer just slightly, then sprinkle the chopped pecans evenly over the top.

Add the butter: Drizzle melted butter evenly over the entire surface, or distribute thin slices across the top to cover as much of the dry mix as possible.

Bake until set: Bake until the top is golden brown and the edges are set, with a slight jiggle remaining in the center, similar to pumpkin pie.

Cool before serving: Let the cake cool for at least 20–30 minutes before serving so the layers can set properly.

Pumpkin Dump Cake Variations (Crunch, Pecan, and More)

Once you’ve mastered the base recipe, it’s easy to tweak this pumpkin dump cake to match your favorite textures and flavors.

Pumpkin Crunch Dump Cake: This is the classic version. Add chopped pecans over the cake mix before baking for a rich, buttery crunch on top.

Pumpkin Pecan Dump Cake: For an even nuttier flavor, increase the amount of pecans or use a mix of chopped and halved pecans for more texture.

Pumpkin Pie Dump Cake: Skip the nuts for a softer topping that lets the smooth, custardy pumpkin layer shine—very similar to pumpkin pie.

Cake Mix Options: Yellow cake mix gives a classic buttery flavor, but vanilla cake mix works beautifully too. For a deeper fall flavor, you can also use spice cake mix.

⭐ Pro Tips

⭐ Use thin butter slices for better coverage: If you’re not melting the butter, slice it very thin and spread it evenly across the top so the cake mix bakes up golden instead of dry.

⭐ Rotate the pan for even browning: About halfway through baking, rotate the pan to help the topping brown evenly, especially if your oven has hot spots.

⭐ Watch the edges for doneness: The edges should be fully set and slightly pulling away from the pan, while the center should be mostly set with just a slight jiggle.

⭐ Let it rest before serving: Giving the cake time to cool helps the custard layer firm up and makes it easier to scoop clean portions.

⭐ Serve warm for best texture: This dessert is at its best slightly warm, when the topping is crisp and the pumpkin layer is soft and creamy.

What to Serve With Pumpkin Dump Cake

This cozy, pumpkin-spiced dessert is rich and comforting, so pairing it with something cool or creamy makes it even better.

Cold + Creamy Toppings: A scoop of vanilla ice cream or a dollop of whipped cream is perfect here. The cool, creamy texture balances the warm, spiced pumpkin base beautifully.

Warm Drinks: Serve it with a cup of coffee, Crockpot Hot Chocolate, or even a spiced latte for the ultimate fall dessert experience.

Sweet Finishes: If you’re building out a dessert spread, pair this with other cozy favorites like Peach Cobbler, Fruit Cocktail Cake, or Million Dollar Pie for a mix of warm and chilled treats.

Storing + Freezing + Make-Ahead

How Long Can You Keep This In The Fridge?

You’ll want to cover it loosely with cling wrap or foil to protect its integrity. This cake can last up to 3-4 days in the fridge.

Can You Freeze This?

Absolutely! This scrumptious pumpkin dump cake with cake mix freezes beautifully and it’s every bit as crave-worthy upon serving. Just let it cool completely before preparing for the freezer. I prefer to double wrap mine in plastic wrap, then in aluminum foil for extra protection. It’ll stay fresh and yummy for up to a month.

For best results slow thaw in the fridge for up to 24 hours before serving. Since this cake contains pumpkin puree, it can only be stored in the freezer for 2-3 months.

Make-Ahead Tips:

This crazy simple pumpkin pie dump cake only has a 10-minute prep time so there really isn’t a bunch of prep to speak of. But, it’s great in the fridge for a few days so you can always make it a day ahead.

Frequently Asked Questions

◆ Why is my pumpkin dump cake runny?
This usually means it needs more bake time. The center should be mostly set with just a slight jiggle—similar to pumpkin pie. It will continue to firm up as it cools.

The butter didn’t fully cover the cake mix. Make sure the butter is evenly distributed so the topping bakes up golden instead of dry.

No. Pumpkin pie filling is already sweetened and spiced, which can throw off both the flavor and the texture of the recipe.

Yes. Let it cool completely, then wrap tightly and freeze for up to 2 months. Thaw in the refrigerator and reheat gently before serving.
