Pumpkin Dump Cake

The first time I made this dump cake was during a chaotic Tuesday when my sister announced she was coming over with her kids and I had zero dessert prepared. I had all these cans in my pantry and remembered my neighbor talking about throwing ingredients together without even mixing properly. Twenty minutes later that golden buttery smell was filling the kitchen and my nephew actually asked if I had been baking all day.

Last autumn I brought this to a potluck and three different people asked for the recipe before they even finished their first bite. Watching friends scoop seconds while sitting around my dining room table made me realize this isnt just dessert its comfort food that brings people together.

Ingredients

• Pumpkin purée: Make sure you are using pure pumpkin not pumpkin pie filling or the flavor will be completely off
• Evaporated milk: This creates a creamier custard layer than regular milk and I have tried both
• Large eggs: Room temperature eggs incorporate better so take them out about 20 minutes before you start
• Granulated sugar: Provides the classic sweetness while balancing the spices
• Light brown sugar: Adds moisture and that subtle caramel note that makes everything taste homemade
• Pumpkin pie spice: If you are feeling adventurous make your own blend with cinnamon ginger nutmeg and allspice
• Salt: Dont skip this it wakes up all the other flavors
• Vanilla extract: Pure vanilla makes a noticeable difference here
• Yellow cake mix: The dry mix creates this incredible crumbly topping that transforms in the oven
• Unsalted butter: Melt it completely but try not to let it get too hot or it will seep through too quickly
• Chopped pecans: These add the perfect crunch but walnuts work beautifully too

Instructions

Get your oven ready:

Preheat to 350°F and give your 9x13 baking dish a thorough coating of butter or cooking spray

Whisk the pumpkin base:

Dump everything from the pumpkin filling section into a large bowl and whisk until completely smooth with no sugar lumps remaining

Spread it evenly:

Pour that gorgeous orange mixture into your prepared dish and use a spatula to create an even layer

Sprinkle the cake mix:

Sprinkle the dry cake mix over the top trying to cover every inch of the pumpkin layer

Drizzle the butter:

Pour that melted butter slowly over the cake mix covering as much surface area as you can

Add the crunch:

Sprinkle your pecans over the top if you are using them

Bake until golden:

Bake for 45 to 50 minutes until the top is a deep golden brown and a toothpick comes out mostly clean

The patience step:

Let it cool for at least 20 minutes because the filling needs time to set up

Save

My mom called me the next day asking how to make it again because she had forgotten to write it down. Now whenever the weather turns crisp this recipe is the first thing that comes to mind.

Make Ahead Magic

You can assemble the entire thing up to a day in advance and keep it covered in the refrigerator. Just add about 10 extra minutes to the baking time since it will be cold going into the oven.

Serving Suggestions

Warm slices are absolute perfection with a scoop of vanilla bean ice cream melting into all those crevices. Sometimes I even drizzle a little salted caramel on top because apparently I cannot leave well enough alone.

Storage and Leftovers

This keeps surprisingly well covered in the refrigerator for up to three days though I doubt it will last that long. The texture actually develops overnight and the spices seem to bloom even more.

• Reheat individual portions in the microwave for about 30 seconds
• The pecans will lose their crunch after a day or two so add fresh ones if that matters to you
• This freezes beautifully for up to two months just thaw overnight in the refrigerator

Save

There is something so satisfying about a dessert that comes together this easily yet tastes like it came from a bakery. Every time I serve it someone always says this tastes like fall in a pan.

Recipe FAQs

→ What makes this different from pumpkin pie?

Unlike traditional pumpkin pie with a rolled crust, this dessert uses dry cake mix sprinkled directly over the pumpkin filling and topped with melted butter. The result is a cobbler-like texture with a soft, custardy pumpkin layer beneath a golden, buttery cake topping that's much simpler to prepare.

→ Can I use fresh pumpkin instead of canned?

Yes, you can substitute homemade pumpkin purée. Roast or steam fresh pumpkin until tender, then purée until smooth. Use 15 ounces (about 2 cups) of well-drained fresh purée, ensuring it's not too watery for the best texture.

→ Why is it called a dump cake?

The name comes from the preparation method—you literally dump ingredients into the baking dish in layers without mixing. First the pumpkin filling, then dry cake mix, then melted butter. No electric mixer or advanced techniques required, making it perfect for beginners.

→ How should I store leftovers?

Store covered in the refrigerator for up to 2 days. The texture remains excellent—just warm individual portions in the microwave for 20-30 seconds before serving. The buttery topping may soften slightly when refrigerated but regains its appeal when reheated.

→ Can I make this dairy-free?

Absolutely. Replace evaporated milk with full-fat coconut milk or almond milk, and use plant-based butter sticks instead of dairy butter. The texture and flavor remain delicious, and no one will notice the difference when served warm.

→ What toppings work well?

Whipped cream, vanilla ice cream, or a dollop of Greek yogurt complement the warm spiced flavors beautifully. Chopped pecans or walnuts add crunch, while a dusting of cinnamon sugar or a drizzle of caramel sauce elevates the presentation.
