Pumpkin Dump Cake

Last November, my sister called at 8 PM asking what to bring to a potluck the next morning. I had a can of pumpkin sitting on my counter from a cancelled pie experiment and a box of cake mix in the pantry. We threw this together in ten minutes while laughing about how it was called a cake but required zero actual cake-baking skills. Her text later that day simply said everyone wants the recipe.

I brought this to a Friendsgiving where the host burned her main dish and everyone was hovering around the buffet awkwardly. Within minutes of setting it down, people were scraping their plates clean and suddenly the evening felt warm and abundant again. Something about dump cakes just makes people feel taken care of, like youre sharing a secret shortcut to comfort.

Ingredients

• 15 oz pumpkin purée: Make sure this is pure pumpkin, not pumpkin pie filling in a can
• 12 oz evaporated milk: This creates a creamier texture than regular milk and helps set the filling
• 3 large eggs: Room temperature eggs incorporate better into the mixture
• 1 cup granulated sugar: Provides sweetness and helps the filling set properly
• 1/2 cup packed light brown sugar: Adds a deeper molasses flavor that complements the pumpkin
• 2 teaspoons pumpkin pie spice: If you only have cinnamon, add a pinch of ginger and nutmeg
• 1/2 teaspoon salt: Essential to balance all the sweetness
• 1 teaspoon vanilla extract: Use pure vanilla for the best flavor
• 1 box yellow cake mix: Do not prepare the mix, just pour it dry over the pumpkin
• 3/4 cup unsalted butter, melted: Salted butter works too, just reduce the salt in the filling slightly
• 1 cup chopped pecans: Toast them for 3 minutes before adding for extra crunch

Instructions

Get your oven ready:

Preheat to 350°F and grease a 9x13 baking dish with butter or cooking spray

Whisk the pumpkin filling:

Combine pumpkin, evaporated milk, eggs, both sugars, spices, salt, and vanilla until completely smooth, about 2 minutes

Spread it evenly:

Pour the mixture into your prepared dish and use a spatula to create a level surface

Add the magic topping:

Sprinkle the dry cake mix over the pumpkin in an even layer, then drizzle melted butter back and forth until mostly covered

Bake until golden:

Bake 45 to 50 minutes until the top is deep golden and set, though the center should still have a slight jiggle

Let it rest:

Cool at least 20 minutes before serving, as the filling needs time to set up properly

Save

My neighbor stopped by while this was baking and stood in my kitchen just inhaling the air for a solid minute. She showed up the next day with her own empty baking dish, admitting she had to try making it immediately after smelling ours. That is the power of pumpkin and butter together.

Make It Your Own

I have swapped pecans for walnuts when thats what I had in the freezer, and once I used half yellow cake mix and half spice cake mix which made it extra cozy. You could also add a handful of white chocolate chips to the topping for a sweet twist.

Serving Suggestions

Warm vanilla ice cream melting over the top creates this incredible temperature contrast. A dollop of freshly whipped cream with a pinch of cinnamon on top feels fancy but takes thirty seconds.

Storage And Reheating

This keeps remarkably well covered in the fridge for up to three days. The texture actually improves overnight as the flavors meld together.

• Reheat individual portions for 20 seconds in the microwave
• Cover the dish with foil and rewarm at 300°F for 15 minutes if serving a crowd
• Bring to room temperature for 30 minutes before serving leftovers

There is something deeply satisfying about a dessert that looks impressive but requires almost zero technique. This is the kind of recipe that makes you feel like you pulled off something magical.

Recipe FAQs

→ What makes this a dump cake?

A dump cake gets its name from the simple method of 'dumping' ingredients into a baking dish without mixing them together. The dry cake mix is poured over the pumpkin filling, then butter is drizzled on top. As it bakes, the butter melts into the cake mix creating a crispy, golden topping while the pumpkin layer bakes into a smooth custard-like consistency underneath.

→ Can I use fresh pumpkin instead of canned?

Yes, you can use fresh pumpkin purée. Roast or steam a sugar pumpkin until tender, then purée the flesh until smooth. Use about 2 cups of fresh purée to replace the 15-ounce can. Just be sure to drain any excess liquid first, as fresh pumpkin can be more watery than canned, which may affect the final texture.

→ How do I know when it's done baking?

The cake is done when the top is golden brown and the butter has fully melted into the cake mix creating a crispy, bubbly surface. Insert a toothpick into the center—it should come out mostly clean but may have some moist crumbs attached. The center should still have a slight jiggle like pumpkin pie when you gently shake the pan.

→ Can I make this ahead of time?

Yes, you can assemble this dessert up to 24 hours in advance. Cover the dish tightly with foil and refrigerate before baking. Add 5-10 minutes to the baking time if baking cold from the refrigerator. Once baked, it also reheats beautifully—just cover with foil and warm in a 350°F oven for 10-15 minutes.

→ What can I serve with pumpkin dump cake?

Warm servings pair beautifully with whipped cream, vanilla ice cream, or even a dollop of Greek yogurt for a tangy contrast. For extra indulgence, drizzle with salted caramel sauce or sprinkle with cinnamon sugar. It's also delicious on its own, served slightly warm so the buttery topping is still slightly crisp.

→ How should I store leftovers?

Cover the baking dish tightly with foil or transfer leftovers to an airtight container. Refrigerate for up to 2 days. The texture remains excellent, though the topping may soften slightly. Bring to room temperature or warm gently in the oven before serving for the best experience.
