This autumn-inspired dessert layers a creamy pumpkin filling with warm spices beneath a buttery yellow cake topping. Simply whisk together pumpkin purée, evaporated milk, eggs, sugars, and pumpkin pie spice, then pour into a baking dish. Sprinkle dry cake mix over the filling, drizzle with melted butter, add pecans if desired, and bake until golden. The result is a warm, comforting treat with a crisp top and soft pumpkin layer underneath.
The name alone made me skeptical when my sister mentioned she was bringing dump cake to Thanksgiving. I'd been making from-scratch pumpkin pie for years, the kind where you roast the sugar pumpkins yourself and debate the merits of different crust techniques. That afternoon, I watched her dump ingredients into a pan while chatting about her kids, barely measuring anything. Two hours later, my cousin took one bite and declared it better than my award-winning pie. Sometimes the uncomplicated approach wins.
Last October, my neighbor knocked on my door holding a bag of pumpkin purée she'd accidentally bought in bulk. We ended up making three dump cakes that afternoon while her toddler played with my dog. There's something almost magical about how the dry cake mix transforms in the oven, bubbling up through the butter in golden patches. We ate it warm from the oven, standing in the kitchen with forks, while rain tapped against the windows.
Ingredients
- 15 oz pumpkin purée: Make sure you're using pure pumpkin not pumpkin pie filling which already has spices and sugar added
- 12 oz evaporated milk: This creates a creamier texture than regular milk and helps the filling set properly
- 3 large eggs: Room temperature eggs incorporate more easily into the mixture
- 1 cup granulated sugar: Balances the natural sweetness of the pumpkin
- 1/2 cup light brown sugar: Adds a subtle molasses depth that white sugar alone can't provide
- 2 teaspoons pumpkin pie spice: I make my own blend with cinnamon ginger nutmeg and a pinch of clove but store-bought works perfectly
- 1/2 teaspoon salt: Crucial for bringing out all the warm spice flavors
- 1 teaspoon vanilla extract: Use real vanilla not imitation it makes a noticeable difference
- 1 box yellow cake mix: Don't overthink this brand any standard 15 ounce box works beautifully
- 3/4 cup unsalted butter melted: Salted butter works too but you might want to reduce the salt in the filling slightly
- 1 cup chopped pecans: Optional but I love the crunch they add against the soft pumpkin layer
Instructions
- Prep your oven and pan:
- Preheat oven to 350°F and give your 9x13 baking dish a thorough coating of butter or cooking spray
- Whisk the pumpkin filling:
- In a large bowl combine pumpkin evaporated milk eggs both sugars pumpkin pie spice salt and vanilla until completely smooth
- Spread the filling:
- Pour the mixture into your prepared dish and use a spatula to create an even layer from edge to edge
- Add the cake layer:
- Sprinkle the dry cake mix over the pumpkin filling trying to distribute it as uniformly as possible
- Drizzle the butter:
- Pour your melted butter evenly over the cake mix doing your best to cover the surface and get those corners
- Add nuts if desired:
- Scatter pecans across the top now if you're 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
- Let it rest:
- Allow the cake to cool for at least 20 minutes before serving so the filling has time to set
My daughter requested this for her birthday instead of cake last year. We served it with vanilla ice cream while she sat surrounded by friends telling stories about college. One of them asked for the recipe and now it shows up at their apartment potlucks every few months. Food travels like that carrying memories from kitchen to kitchen.
Making It Your Own
The beauty of a dump cake is how forgiving it is. I've added a teaspoon of cinnamon to the pumpkin filling when I wanted extra warmth and once stirred in some chopped crystallized ginger. One friend mixes white chocolate chips into the pecans. You can swap the nuts for walnuts or leave them out entirely if allergies are a concern.
Serving Suggestions
While this is delicious on its own a dollop of lightly sweetened whipped cream or a scoop of vanilla ice cream takes it over the top. I've also served it with a drizzle of salted caramel sauce when I really wanted to impress. For breakfast the next morning cold leftovers are strangely satisfying with coffee.
Storage Tips
This cake keeps remarkably well covered in the refrigerator for up to two days though the topping will lose some of its crispness. Reheat individual portions in the microwave for about 20 seconds to bring back that fresh-baked texture. You can also freeze the whole cake wrapped tightly for up to three months and thaw it overnight in the refrigerator.
- Let the cake come to room temperature before wrapping for storage to prevent condensation
- Cut portions before freezing so you can grab exactly what you need
- Reheat frozen pieces directly from the freezer just add a minute to the microwave time
This is the recipe I turn to when I need something comforting but don't have the energy for complicated baking. It's never failed me not even once.

Store covered in the refrigerator for up to 2 days. The texture remains excellent when reheated in the microwave for about 30 seconds.
