Pumpkin Dump Cake

The first time I made this dump cake was during a chaotic November when my sister announced she was bringing her new boyfriend to Thanksgiving dinner. I had zero time for anything complicated. My neighbor whispered this recipe as she headed to her own holiday prep, and something about just dumping ingredients together and letting the oven do the work felt like permission to breathe.

That Thanksgiving dinner my sister took one bite and said this was better than our grandmothers actual pumpkin pie which felt like treason but also the highest compliment. Now I make it every autumn and honestly the best part might be how my house smells while its baking like cinnamon and memories and possibility all mingling together.

Ingredients

• 15 oz pumpkin purée: Fresh purée works too but honestly the canned stuff gives you such consistent results and who needs more pressure in November
• 12 oz evaporated milk: This is the secret ingredient that makes the filling so creamy and rich without any actual culinary heavy lifting
• 3 large eggs: Room temperature eggs incorporate so much better into your pumpkin mixture for that silky smooth texture
• 1 cup granulated sugar: You need this sweetness to balance out all those earthy pumpkin notes
• 1/2 cup packed light brown sugar: The molasses here adds such lovely depth and a subtle caramel undertone
• 2 teaspoons pumpkin pie spice: I make my own blend but store bought works perfectly fine
• 1/2 teaspoon salt: This tiny amount wakes up all the other flavors and keeps things from tasting flat
• 1 teaspoon vanilla extract: Use real stuff here it absolutely makes a difference in the final flavor
• 1 box yellow cake mix: No shame in the cake mix game here it creates this amazing tender crumb that pairs perfectly with pumpkin
• 3/4 cup unsalted butter melted: The butter needs to be genuinely melted and hot for that gorgeous golden crust
• 1 cup chopped pecans: Totally optional but I love the crunch and they toast up so beautifully in the oven

Instructions

Preheat your oven:

Set it to 350°F and grease a 9x13 baking dish with butter or cooking spray. Do not skip this step or you will regret every second of cleanup later.

Whisk the pumpkin filling:

In a large bowl combine pumpkin evaporated milk eggs both sugars pumpkin pie spice salt and vanilla. Whisk until everything is completely smooth and no sugar lumps remain.

Spread the pumpkin mixture:

Pour into your prepared baking dish and use a spatula to create an even layer. The mixture should look silky and smooth like a proper pumpkin pie filling.

Add the cake mix:

Sprinkle the dry cake mix evenly over the entire surface. Do not stir or mix this layer just let it settle gently on top of the pumpkin.

Drizzle the butter:

Pour your melted butter slowly and evenly across the cake mix. Try to cover as much surface area as possible for that golden buttery crust.

Add the pecans:

Sprinkle chopped pecans over the top if you are using them. They will toast beautifully while baking and add such nice texture.

Bake until golden:

Bake for 45 to 50 minutes until the top is golden brown and a toothpick comes out mostly clean. The center might still seem slightly jiggly and that is perfectly okay.

Let it cool:

Wait at least 20 minutes before serving. This gives the filling time to set up properly so you get nice clean slices instead of pumpkin soup.

Last year I made this for a Friendsgiving and someone asked if I could make it again for Christmas dinner. Then New Years Eve. Then Super Bowl Sunday because apparently it is not just for holidays anymore. It has become this thing people request and I love that something so simple can feel so special to the people I feed.

Serving Suggestions

Warm is definitely the way to serve this dessert. The contrast between the slightly crisp buttery topping and the soft creamy pumpkin filling is absolute perfection. A scoop of vanilla ice cream melting into the warm pumpkin layer creates this incredible sauce that people will fight over. Sometimes I add a dusting of powdered sugar right before serving just to make it look like I tried harder than I actually did.

Make Ahead Magic

You can absolutely assemble this entire dump cake ahead of time and keep it in the refrigerator for up to 24 hours before baking. This is honestly a game changer for dinner parties and holiday gatherings. Just pull it out about 30 minutes before you plan to bake it so it is not shocking cold when it hits the oven. You might need to add a few extra minutes to the baking time but the result is just as delicious.

Storage Tips

This cake actually tastes even better on day two after all the flavors have had time to get properly acquainted. Store leftovers covered in the refrigerator and they will stay fresh for up to two days. The texture becomes slightly more dense and almost fudge like which is kind of magical in its own way. You can also freeze individual portions for those emergency dessert cravings.

• Always reheat refrigerated portions because the texture transforms from good to extraordinary
• Place a piece of parchment paper between stacked portions so they do not stick together
• Let frozen pieces thaw overnight in the refrigerator before reheating

This recipe is proof that sometimes the simplest most unpretentious desserts become the ones people remember most. There is something so honest about dumping ingredients in a dish and ending up with something that brings people together around the table.

Recipe FAQs

→ What makes a dump cake different from regular cake?

A dump cake gets its name from the simple preparation method where ingredients are literally dumped into the pan without mixing batter separately. The dry cake mix sits on top of the filling, and melted butter creates a crispy, golden topping as it bakes.

→ 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 until smooth. Use 1 ¾ cups of fresh purée to replace the 15-ounce can. Make sure to drain excess liquid if the fresh purée seems watery.

→ How should I store leftover pumpkin dump cake?

Store covered in the refrigerator for up to 2 days. The texture remains excellent when reheated—warm individual portions in the microwave for 30-60 seconds or serve cold if you prefer. The topping stays fairly crisp even after refrigeration.

→ Can I make this dump cake ahead of time?

You can assemble the entire dish up to 24 hours before baking and store it covered in the refrigerator. Add an extra 5-10 minutes to the baking time if baking cold. Alternatively, bake it a day ahead and reheat before serving.

→ What toppings work well with pumpkin dump cake?

Warm servings pair beautifully with whipped cream, vanilla ice cream, or a drizzle of salted caramel sauce. For extra indulgence, sprinkle powdered sugar over the top just before serving or add a scoop of cinnamon ice cream.

→ Is it normal for the center to seem slightly soft?

Yes, this is completely normal and expected. The pumpkin layer remains custard-like even when fully baked, similar to pumpkin pie filling. The cake topping should be golden brown and crisp, while the pumpkin set is soft and creamy.
