Pumpkin dump cake is what you make when you want all the warm flavor of pumpkin pie without rolling dough, crimping a crust, or worrying about whether the center will set. It has a soft, warmly spiced pumpkin layer on the bottom and a buttery cake topping that turns golden and crisp in the oven.
This easy pumpkin dessert requires about 15 minutes of preparation and feeds a crowd, which makes it a great choice for Thanksgiving, fall parties, potlucks, and casual family dinners. Serve it warm with vanilla ice cream or chilled with whipped cream. Either way, make sure your spoon reaches both layers in every serving.
Unlike most dump cake recipes, the pumpkin layer needs to be mixed before it goes into the baking dish. After that, the method is as simple as sprinkling dry cake mix over the filling, adding pecans, and pouring melted butter across the top. Do not stir the layers together. The separation is what creates the creamy base and crisp topping.

What Is a Dump Cake?

A dump cake is an easy dessert made by layering filling, dry cake mix, and butter in a baking dish. The ingredients are not mixed into a traditional cake batter. As the dessert bakes, the butter melts into the dry mix while moisture rises from the filling below.
The finished texture falls somewhere between a cobbler, a cake, and a crisp. The top becomes buttery and golden while the filling underneath stays soft.
Fruit dump cakes usually begin with canned fruit or pie filling. Pumpkin dump cake is a little different because plain pumpkin purée needs eggs, milk, sugar, and spices to turn it into a rich custard.
You will need one bowl to prepare the pumpkin mixture, but the rest of the recipe is layered directly in the baking dish.

What Does Pumpkin Dump Cake Taste Like?

The bottom layer tastes like soft pumpkin pie filling with cinnamon, ginger, nutmeg, and cloves. The topping is buttery, slightly crisp, and tender in the places where it meets the pumpkin.
Chopped pecans bring a toasted, nutty bite that helps balance the creamy filling. A small amount of salt keeps the dessert from tasting overly sweet.
This is not a fluffy pumpkin cake. It is meant to have two different textures: a spoonable pumpkin custard underneath and a crumbly cake topping above.

Ingredients You’ll Need

Pumpkin Purée

Use one 15-ounce can of 100 percent pure pumpkin purée. Do not use pumpkin pie filling. Pumpkin pie filling already contains sweeteners and spices, which can make the dessert too sweet and throw off the texture.

Evaporated Milk

Evaporated milk gives the filling a creamy texture without making it heavy. Make sure you are using evaporated milk, not sweetened condensed milk. Sweetened condensed milk is much thicker and contains added sugar.

Eggs

Three large eggs help the pumpkin layer set into a soft custard. Bring the eggs to room temperature if you have time so they blend easily into the filling.

Brown Sugar

Brown sugar adds sweetness along with a light caramel flavor. Either light or dark brown sugar will work. Dark brown sugar produces a slightly deeper molasses taste.

Vanilla Extract

Vanilla softens the earthy flavor of the pumpkin and brings the cake and custard layers together.

Pumpkin Pie Spice

Pumpkin pie spice usually contains cinnamon, ginger, nutmeg, cloves, and sometimes allspice. You can use a store-bought blend or make your own.

Ground Cinnamon

A little extra cinnamon gives the filling a fuller fall flavor without overpowering the pumpkin.

Salt

Salt balances the sugar and butter. Do not leave it out, especially if you are using unsalted butter.

Yellow Cake Mix

Yellow cake mix creates a classic buttery topping. Use the dry mix directly from the box. Do not prepare it according to the package directions.
A 15.25-ounce box is ideal, but a box that is a little smaller will still work. Yellow cake mix gives the dessert a mild flavor that lets the pumpkin and spices stand out.

Chopped Pecans

Pecans add texture and become toasted as the cake bakes. Roughly chop them so you get a mixture of small pieces and larger bites.
If you are serving someone with a nut allergy, leave them out. The cake will still taste good.

Butter

Two sticks of melted butter moisten the cake mix and help the surface turn crisp and golden. Pour it slowly so as much of the dry mixture as possible gets covered.

Yellow Cake Mix or Spice Cake Mix?

Yellow cake mix is my first choice because it gives the topping a warm, buttery flavor without adding too much spice. It also produces a nice contrast between the golden topping and the orange pumpkin filling.
Spice cake mix works if you prefer a stronger cinnamon and clove flavor. If you use it, you may want to reduce the pumpkin pie spice in the filling to 1½ teaspoons.
White cake mix can also be used, although the flavor will be lighter. Butter pecan cake mix is another good option if you enjoy a stronger nutty taste.

How to Make Pumpkin Dump Cake

1. Prepare the Baking Dish

Preheat the oven to 350°F. Lightly coat a 9 x 13-inch baking dish with nonstick spray or a thin layer of softened butter.
A ceramic, glass, or light-colored metal pan will work. A metal pan may bake the edges a little faster, so begin checking the cake a few minutes early.

2. Mix the Pumpkin Filling

Add the pumpkin purée, evaporated milk, eggs, brown sugar, vanilla, pumpkin pie spice, cinnamon, and salt to a large bowl.
Whisk until the eggs are completely blended and the mixture looks smooth. The filling will be thinner than pumpkin pie filling from a can. That is normal.

3. Pour the Filling into the Pan

Pour the pumpkin mixture into the prepared baking dish. Spread it into an even layer, making sure it reaches every corner.

4. Add the Dry Cake Mix

Sprinkle the dry yellow cake mix evenly over the pumpkin layer.
Work slowly and cover the entire surface, including the edges and corners. Break apart any large clumps with your fingers.
Do not stir the cake mix into the pumpkin.

5. Add the Pecans

Scatter the chopped pecans evenly over the cake mix. Keeping the pieces evenly spaced will help each serving get a little crunch.

6. Pour on the Butter

Slowly drizzle the melted butter across the entire surface. Pay close attention to the corners and any visibly dry areas.
A few small dry spots are fine, but large uncovered patches may remain powdery after baking. Use the back of a spoon to gently guide butter over those areas without stirring down into the pumpkin.

7. Bake

Bake for 50 to 60 minutes, or until the top is deep golden brown and the pumpkin filling is mostly set.
The center may have a slight jiggle when you gently move the pan, but it should not look wet or slosh from side to side.

8. Cool Before Serving

Place the pan on a wire rack and let the cake cool for at least 30 minutes.
The pumpkin layer continues to set as it cools. Serving it straight from the oven can make the filling look too loose, even when it has baked properly.

The Secret to an Evenly Baked Dump Cake

The biggest challenge with any dump cake is preventing dry pockets of cake mix. This usually happens when the butter is poured too quickly or concentrated in only a few places.
For better coverage:

• Sprinkle the cake mix in a thin, level layer.
• Break apart dry lumps before adding the butter.
• Drizzle the butter slowly in narrow lines.
• Cover the edges and corners, not only the center.
• Gently spread pooled butter with the back of a spoon.
• Do not stir through the pumpkin layer.

Some bakers prefer covering the surface with very thin slices of cold butter. That method works, but the slices need to be extremely thin and placed close together. Melted butter is faster and makes it easier to see which areas still need coverage.

How to Tell When Pumpkin Dump Cake Is Done

Pumpkin dump cake is ready when:

• The topping is golden brown.
• The pecans smell toasted.
• The edges look set.
• The center has only a slight wobble.
• There is no pool of liquid in the middle.
• A thermometer inserted into the pumpkin layer reads about 175°F.

Do not test it with a toothpick as you would a regular cake. The pumpkin base is supposed to remain moist, so the toothpick will not come out completely clean.
If the top is browning before the center sets, loosely cover the dish with foil and continue baking for another 5 to 10 minutes.

Tips for the Best Pumpkin Dump Cake

Use Pure Pumpkin

Check the label carefully. Pure pumpkin and pumpkin pie filling are often placed next to each other at the grocery store, but they are not interchangeable in this recipe.

Sprinkle the Cake Mix Evenly

A thick mound of cake mix will have a harder time absorbing butter and moisture. Use a measuring cup or clean hands to distribute it across the entire pan.

Do Not Stir the Layers

Stirring turns the filling and cake mix into a heavy batter. Keep the pumpkin, cake mix, pecans, and butter in separate layers.

Cover the Dry Mix with Butter

The cake mix needs fat to brown and form a crumbly topping. Drizzle the butter slowly and check the pan from several angles for large dry patches.

Let It Rest

The filling will be very soft when the pan first comes out of the oven. Give it at least 30 minutes to settle before serving. For tidy squares, cool the cake completely and refrigerate it before slicing.

Use Fresh Spices

Ground spices lose their flavor over time. If your pumpkin pie spice has been sitting in the cabinet for several years, replace it before holiday baking begins.

Toast the Pecans for More Flavor

This step is optional, since the pecans will toast in the oven. If you prefer a stronger nutty flavor, toast them in a dry skillet for 3 to 5 minutes before adding them to the cake.

Common Pumpkin Dump Cake Mistakes

Stirring the Topping into the Filling

A dump cake depends on its layers. Once the dry mix is added, leave it on top.

Using Pumpkin Pie Filling

Pumpkin pie filling changes the sweetness and seasoning. Use plain canned pumpkin so you can control both.

Using Sweetened Condensed Milk

Evaporated milk and sweetened condensed milk are not the same product. Sweetened condensed milk would make this recipe far too sweet and thick.

Leaving Large Areas of Dry Cake Mix

Small dry crumbs are normal, but wide powdery patches mean the butter was not spread evenly.

Removing the Cake Too Soon

The surface can appear done before the center has set. Look for a golden topping and a center that no longer moves like liquid.

Cutting It While It Is Very Hot

Warm pumpkin dump cake is meant to be spooned into bowls. If you want neat slices, chill it first.

Easy Variations

Pumpkin Spice Dump Cake

Replace the yellow cake mix with spice cake mix. Reduce the pumpkin pie spice to 1½ teaspoons if you do not want the spice flavor to become too strong.

Pumpkin Pecan Dump Cake

Increase the chopped pecans to 1½ cups. You can also add a handful of pecan halves across the top for a pretty finish.

Pumpkin Caramel Dump Cake

Drizzle caramel sauce over each serving instead of adding it before baking. This gives you better control over the sweetness and keeps the topping crisp.

Chocolate Chip Pumpkin Dump Cake

Sprinkle ¾ cup semisweet chocolate chips over the dry cake mix before adding the pecans and butter.

Nut-Free Pumpkin Dump Cake

Leave out the pecans and prepare the remaining recipe as written. For extra crunch, sprinkle crushed cinnamon graham crackers over individual servings just before eating.

Gluten-Free Pumpkin Dump Cake

Use a gluten-free yellow cake mix and check that every packaged ingredient is labeled gluten-free. The baking time may vary slightly depending on the cake mix.

Dairy-Free Pumpkin Dump Cake

Use full-fat canned coconut milk in place of the evaporated milk and a plant-based butter made for baking. Coconut milk may add a faint coconut taste.

How to Serve Pumpkin Dump Cake

This dessert can be served warm, at room temperature, or chilled. The texture changes slightly at each temperature.
Warm pumpkin dump cake is very soft and works best spooned into shallow bowls. At room temperature, the filling is firmer but still creamy. Chilled cake can be cut into cleaner squares.
Try it with:

• Vanilla ice cream
• Cinnamon ice cream
• Lightly sweetened whipped cream
• Maple whipped cream
• Caramel sauce
• Chopped toasted pecans
• A dusting of cinnamon
• A warm cup of coffee
• Hot apple cider

My favorite way to serve it is slightly warm with a small scoop of vanilla ice cream. The cold ice cream softens over the crisp cake topping and creamy pumpkin layer.

Can You Make Pumpkin Dump Cake Ahead of Time?

Yes. Pumpkin dump cake is a good make-ahead dessert because the pumpkin layer firms as it chills.
Bake the cake as directed, let it cool, cover the dish, and refrigerate it overnight. Serve it chilled, allow it to sit at room temperature for about 20 minutes, or warm individual portions before serving.
If you want the topping to remain as crisp as possible, wait until the cake has cooled before covering it.

How to Store Pumpkin Dump Cake

Because this dessert contains eggs and evaporated milk, it should be refrigerated. Let it cool, cover the baking dish tightly, and store it in the refrigerator for up to four days.
Perishable leftovers should be refrigerated within two hours, according to FoodSafety.gov.
The topping will soften slightly during storage, but the flavor remains good.

Can You Freeze Pumpkin Dump Cake?

Yes. Let the cake cool completely, then transfer individual portions to freezer-safe containers. Freeze for up to two months for the best texture.
Thaw the cake overnight in the refrigerator. The topping may be softer after freezing, so warm the portions uncovered in the oven or air fryer if you want to bring back some crispness.
Do not move a cold glass baking dish directly into a hot oven. The sudden temperature change could cause the dish to crack.

How to Reheat Pumpkin Dump Cake

To reheat one serving, microwave it for 20 to 30 seconds.
To reheat several portions, place them in an oven-safe dish and warm at 325°F for about 10 to 15 minutes. Leave the dish uncovered if you want the topping to become slightly crisp again.

Frequently Asked Questions

Does pumpkin dump cake need to be refrigerated?

Yes. Pumpkin dump cake contains eggs and evaporated milk, so leftovers should be covered and refrigerated. Store them for up to four days.

Can I use pumpkin pie filling instead of pumpkin purée?

It is best to use pure pumpkin purée. Pumpkin pie filling already contains sugar and spices, so using it would change the sweetness, flavor, and texture of the recipe.

Why is my pumpkin dump cake still runny?

The cake may need more baking time, or it may have been served before the filling had time to set. Bake until the center has only a slight jiggle, then cool the cake for at least 30 minutes. It will become firmer as it cools.

Why does my dump cake have dry cake mix on top?

Dry patches happen when the melted butter does not cover enough of the cake mix. Pour the butter slowly across the whole pan and gently guide it over large dry areas with the back of a spoon.

Can I mix the cake mix with the pumpkin filling?

No. Keep the cake mix in a separate layer on top of the pumpkin. Stirring the two together changes the intended custard-and-crumble texture.

Do I make the boxed cake mix according to the package?

No. Sprinkle the dry mix directly from the box over the pumpkin layer. Do not add the eggs, oil, or water listed on the cake mix package.

Can I use spice cake mix?

Yes. Spice cake mix gives the topping a stronger fall flavor. Consider reducing the pumpkin pie spice in the filling to 1½ teaspoons so the cloves and cinnamon do not overpower the pumpkin.

Can I make pumpkin dump cake without pecans?

Yes. Simply leave them out. The topping will have less crunch, but the cake will still bake correctly.

Can I use fresh pumpkin purée?

Yes, but it needs to have a thick texture similar to canned pumpkin. Watery homemade purée can prevent the filling from setting properly. Drain it through cheesecloth if needed before measuring 1¾ cups.

Can I substitute regular milk for evaporated milk?

Whole milk can be used, but evaporated milk creates a richer, creamier filling. Half-and-half is another good substitute. Avoid skim milk because it can make the base less rich.

Is pumpkin dump cake supposed to be gooey?

The pumpkin layer should be soft and custardy, not watery. The top should be golden, buttery, and slightly crisp. The filling will firm up more as the dessert cools.

Can pumpkin dump cake be left out overnight?

No. Since it contains dairy and eggs, it should not sit at room temperature overnight. Cover and refrigerate it within two hours.

Is pumpkin dump cake served warm or cold?

It can be served either way. Warm servings are softer and best scooped into bowls. Chilled cake is firmer and easier to cut into squares.

Can I prepare it the night before Thanksgiving?

Yes. Bake, cool, cover, and refrigerate it overnight. Serve chilled or warm individual servings shortly before dessert.

How many people does a 9 x 13-inch pumpkin dump cake serve?

One pan makes about 12 generous servings or 15 smaller servings. If several desserts are available, you may be able to serve up to 18 people.

What is the difference between pumpkin dump cake and pumpkin pie?

Pumpkin pie has a pastry crust and smooth custard filling. Pumpkin dump cake replaces the pastry with a buttery cake mix and pecan topping. It is easier to assemble and can be served with a spoon.

What is the best topping for pumpkin dump cake?

Vanilla ice cream is especially good with warm pumpkin dump cake. Whipped cream, caramel sauce, maple whipped cream, and toasted pecans are also tasty choices.
