Pumpkin Dump Cake

The kitchen was already wrapped in that distinctive autumn chill when my roommate tossed a can of pumpkin on the counter and said we needed dessert for movie night. Neither of us wanted to measure flour or wait for dough to chill, so we threw together this dump cake with the kind of reckless abandon that usually leads to disaster. Instead, we pulled something golden and bubbling from the oven that disappeared before the opening credits even rolled. Now it's the only thing I make when November shows up on the calendar.

Last year I brought this to a Friendsgiving where someone had already signed up for pumpkin pie, and I honestly considered turning back around. But the host took one bite of the warm, buttery topping against that spiced pumpkin base and declared it better than any pie she'd ever made. Now I get text messages in October asking if I'm bringing the dump cake, and I've learned to double the recipe because people go back for seconds while it's still cooling on the counter.

Ingredients

• Pumpkin purée: Use pure pumpkin, not pie filling—this is the creamy foundation that carries all those warm spices
• Evaporated milk: Creates a richer, silkier texture than regular milk and helps the custard-like layer set perfectly
• Large eggs: Room temperature eggs blend more smoothly into the mixture for even consistency
• Granulated and brown sugar: The combination gives you sweetness with just enough molasses depth from the brown sugar
• Pumpkin pie spice: Your shortcut to autumn warmth in a single spoonful
• Salt: Just a pinch wakes up all the spices and keeps the sweetness from becoming cloying
• Vanilla extract: Rounds out the flavors and adds that comforting bakery aroma
• Yellow cake mix: Do not add the ingredients listed on the box—dump it straight from the bag
• Unsalted butter: Melted completely so it can seep through every bit of dry cake mix
• Pecans: Optional but highly recommended for that satisfying crunch against soft cake

Instructions

Get everything ready:

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

Whisk the pumpkin base:

In a large bowl, combine pumpkin purée, evaporated milk, eggs, both sugars, pumpkin pie spice, salt, and vanilla until the mixture is completely smooth and no streaks remain

Start the layers:

Pour the pumpkin mixture into your prepared dish and spread it into an even layer

Add the magic topping:

Sprinkle the dry cake mix over the pumpkin filling, then drizzle melted butter evenly across the surface

Bake until golden:

Bake for 45 to 50 minutes until the top is golden brown and set, with some bubbling around the edges

Let it rest:

Cool for at least 20 minutes before serving—this helps the layers settle and makes scooping much easier

Save

My sister texted me at midnight one night saying she'd just eaten a cold square straight from the fridge with a fork, standing in her kitchen in her pajamas. That's when I realized this isn't just a party dessert—it's the kind of comfort food that calls to you from the other room.

Make It Your Own

Swap pecans for walnuts or leave them out entirely if you're feeding someone with allergies. The butter and cake combo still delivers plenty of texture without any nuts at all.

Serving Suggestions

Warm slices with vanilla ice cream create that perfect hot-cold contrast that makes people close their eyes and make sounds. A dollop of whipped cream and a sprinkle of cinnamon never hurt anyone either.

Storage and Make-Ahead Tips

This actually tastes better the next day as the flavors meld and the topping softens slightly. Cover tightly and refrigerate for up to two days, then warm individual portions in the microwave.

• Wrap the dish well if freezing—it keeps for up to three months
• Bring to room temperature before reheating for the best texture
• The butter will separate if frozen, but everything comes back together beautifully once warmed

There's something deeply satisfying about a dessert that looks and tastes impressive but barely requires any effort at all.

Recipe FAQs

→ What makes this different from pumpkin pie?

Instead of a traditional pastry crust, this dessert uses a dry cake mix sprinkled over the pumpkin filling and topped with melted butter. The butter creates a crisp, golden topping that contrasts with the smooth pumpkin layer underneath.

→ Can I make this ahead of time?

Yes, bake it up to a day in advance and store covered in the refrigerator. Reheat individual portions in the microwave or serve at room temperature. The texture holds well for 2 days when properly stored.

→ Why is it called a dump cake?

The name comes from the simple method—ingredients are layered or dumped into the dish without complex mixing. The dry cake mix gets poured over the filling, then melted butter is drizzled on top to create the crust during baking.

→ Can I use fresh pumpkin instead of canned?

Yes, use 2 cups of well-cooked and puréed fresh pumpkin. Make sure to drain excess moisture by letting it sit in a sieve for 30 minutes before using, as fresh pumpkin tends to be more watery than canned.

→ What can I substitute for evaporated milk?

Try coconut milk for a subtle tropical note, or use half-and-half for a richer result. For dairy-free versions, look for plant-based evaporated milk alternatives or use full-fat coconut milk from a can.

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

The top should be golden brown and slightly crispy. A toothpick inserted into the center will come out mostly clean but may have moist crumbs attached. The pumpkin layer should be set but still slightly jiggly like pumpkin pie filling.
