Why You Should Try This Pumpkin Dump cake Recipe

This Pumpkin Dump cake Recipe gives you all the classic pumpkin pie flavor without rolling a single pie crust. You stir the filling in one bowl, sprinkle cake mix on top, drizzle butter, and the oven does the rest.

The texture hits that sweet spot between soft pumpkin custard and crisp, buttery crumble. It works for potlucks, holidays, or “I just want pumpkin dessert and I want it soon” nights.

My whole family scraped the pan clean and argued over the last corner piece, so I baked a second one the next day ★★★★★

Ingredients You’ll Need

Pumpkin layer

1 can (15 ounces) pumpkin puree
- Use 100% pumpkin, not pumpkin pie filling. I like Libby’s for consistent texture.
1 can (12 ounces) evaporated milk
- Any brand works; use full fat for the creamiest result.
3 large eggs
3/4 cup granulated sugar
1/4 cup light brown sugar, packed
2 teaspoons pumpkin pie spice
- Or mix 1 1/2 teaspoons cinnamon, 1/4 teaspoon nutmeg, 1/4 teaspoon ginger, 1/8 teaspoon cloves.
1 teaspoon pure vanilla extract
1/2 teaspoon fine sea salt

Cake topping

1 box yellow cake mix (about 15.25 ounces)
- Spice cake mix also works if you want extra warm flavor.
3/4 cup unsalted butter, melted and slightly cooled
- Use real butter, not margarine, for best flavor.
1/2 cup chopped pecans or walnuts (optional but tasty)

Optional finishing touches

Whipped cream or whipped topping
Vanilla ice cream
Caramel sauce
Extra sprinkle of cinnamon or pumpkin pie spice

Pantry shortcuts and substitutions

Swap evaporated milk with 1 1/2 cups half-and-half in a pinch.
Use coconut milk from a can for a dairy-light version, and use oil instead of butter if needed.
Use gluten free yellow cake mix to keep it gluten friendly.

Equipment list

9×13 inch baking dish (glass or metal both work)
Large mixing bowl
Whisk or sturdy spatula
Measuring cups and spoons
Small bowl or measuring cup for melting butter
Cooling rack
Offset spatula or large spoon for serving

Tips & Tricks

Grease the baking dish well so the pumpkin layer releases easily.
Whisk the pumpkin filling until completely smooth so no streaks of egg remain.
Sprinkle the dry cake mix evenly over the pumpkin layer; do not stir it in.
Drizzle the melted butter slowly and evenly so it soaks into as much cake mix as possible.
Add a few dry spots of cake mix with a light mist of cooking spray or a tiny drizzle of extra butter.
Bake until the center barely jiggles and the top looks golden and crisp.
Let the Pumpkin Dump cake Recipe cool at least 20 to 30 minutes so the custard sets.
Serve warm or at room temperature; chill leftovers for a firmer, more sliceable texture.
Use a metal pan if you want a slightly crisper top, or glass for a softer set.
Line the pan with parchment if you want easier cleanup and neater squares.

How to Make Pumpkin Dump cake Recipe

Step 1: Mix the pumpkin filling

Preheat your oven to 350°F and grease a 9×13 inch baking dish with butter or cooking spray. In a large bowl, add pumpkin puree, evaporated milk, eggs, granulated sugar, brown sugar, pumpkin pie spice, vanilla, and salt. Whisk until the mixture looks smooth and glossy with no streaks of egg or spice.

Pour the pumpkin mixture into the prepared baking dish and spread it into an even layer. Tap the dish gently on the counter to pop any large air bubbles.

Step 2: Add the cake mix layer

Open the box of yellow cake mix and break up any big clumps with your fingers. Sprinkle the dry cake mix evenly over the pumpkin layer, covering the surface from edge to edge. Aim for a thin, even blanket of mix so the topping bakes evenly.

If you use nuts, scatter the chopped pecans or walnuts over the cake mix. Press them very lightly with your hand so they nestle into the dry mix.

Step 3: Drizzle the butter

Melt the butter in a microwave safe bowl or small saucepan until fully liquid, then let it cool 1 to 2 minutes. Slowly drizzle the melted butter over the entire surface of the cake mix. Try to hit as many dry spots as possible so the topping turns crisp and golden.

If a few tiny dry patches remain, leave them; they often still toast nicely. You can spritz them with a bit of cooking spray if they look stubbornly dry.

Step 4: Bake to golden perfection

Place the baking dish on the center rack of the oven. Bake at 350°F for 40 to 50 minutes, until the top looks golden brown and the edges bubble slightly. The center should jiggle just a bit, like pumpkin pie, but not slosh.

If the top browns too quickly, tent the pan loosely with foil near the end of baking. Check doneness by inserting a knife near the center; it should come out mostly clean, with some soft pumpkin but no raw liquid.

Step 5: Cool and serve

Set the Pumpkin Dump cake Recipe on a cooling rack and let it rest at least 20 to 30 minutes. This rest time helps the pumpkin layer thicken and hold together when you scoop it. Serve warm with whipped cream or vanilla ice cream for a soft, spoonable dessert.

Chill it for a few hours if you prefer cleaner slices that hold their shape. Add a drizzle of caramel sauce and a sprinkle of cinnamon if you want extra fall flair.

What to Serve with Pumpkin Dump cake Recipe

Serve this Pumpkin Dump cake Recipe warm with a big scoop of vanilla ice cream so the cold cream melts into the warm, spiced pumpkin. A dollop of lightly sweetened whipped cream also pairs nicely and keeps the dessert from feeling too heavy. Offer fresh fruit on the side, like sliced apples or pears, to add a bit of brightness.

You can also pair it with hot drinks like coffee, chai, hot chocolate, or spiced herbal tea for a cozy dessert spread. If you serve it at brunch, add yogurt and granola on the side and call it “breakfast dessert,” which I fully support.
