Pumpkin Dump cake Recipe tastes like a cross between a spiced pumpkin pie and a buttery crumb cake, with a tender custardy base and a crunchy, caramelized top. It works perfectly for busy holiday cooks, potlucks, or anyone who wants a cozy fall dessert on the table in about an hour. I tested this version so many times that my neighbors started “checking on me” right around dessert time.

Ingredients You’ll Need

Pumpkin filling

1 can (15 ounces) pure pumpkin puree
- Use 100% pumpkin, not pumpkin pie mix. Libby’s or store brand both work.
1 can (12 ounces) evaporated milk
- Evaporated milk gives a rich, custardy texture.
3 large eggs, room temperature
- Room temp eggs mix more smoothly.
3/4 cup granulated sugar
1/4 cup light brown sugar, packed
- Brown sugar adds a caramel note.
2 teaspoons pumpkin pie spice
- Or use 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)
- Any standard brand works; spice cake mix also tastes great.
1 teaspoon ground cinnamon
- Optional, but it boosts the fall flavor.
3/4 cup chopped pecans or walnuts
- Toasted nuts add crunch; skip if you need a nut free dessert.
1 cup (2 sticks) unsalted butter, melted and slightly cooled
- Use real butter, not margarine, for best flavor.

Optional toppings

Whipped cream or whipped topping
Vanilla ice cream
Caramel sauce
A pinch of cinnamon or nutmeg for sprinkling

Equipment

9×13 inch baking dish (glass or metal)
Large mixing bowl
Whisk and rubber spatula
Measuring cups and spoons
Small bowl for mixing cinnamon with cake mix
Knife or offset spatula for serving

Tips & Tricks

Grease the baking dish lightly with butter or nonstick spray so slices lift out cleanly.
Use pumpkin puree at room temperature so it blends smoothly with the eggs and milk.
Stir the pumpkin filling until it looks silky and uniform, with no streaks of egg.
Sprinkle the dry cake mix evenly over the pumpkin layer; do not stir it in.
Drizzle the melted butter slowly and evenly over the cake mix so fewer dry spots remain.
If a few dry patches stay on top, they still bake into a crunchy, cobbler style topping.
Bake on the middle rack so the bottom sets and the top browns without burning.
Check doneness near the center; the pumpkin layer should jiggle slightly but not slosh.
Let the Pumpkin Dump cake Recipe cool at least 20 to 30 minutes so it slices more neatly.
Serve warm for a softer, spoonable dessert or chilled for a firmer, bar style texture.
Swap yellow cake mix with spice cake mix when you want extra spice flavor.
Omit nuts or replace them with rolled oats if you cook for someone with nut allergies.

How to Make Pumpkin Dump cake Recipe

Step 1: Preheat the oven and prep the pan

Set your oven to 350°F (175°C).
Lightly grease a 9×13 inch baking dish with butter or nonstick spray.
Set the pan aside while you mix the pumpkin filling.

Step 2: Mix the pumpkin filling

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

Step 3: Add the cake mix layer

In a small bowl, stir the dry cake mix with the ground cinnamon.
Sprinkle the cake mix evenly over the pumpkin layer, covering the surface from corner to corner.
Do not stir; you want a distinct pumpkin layer on the bottom and cake layer on top.

Step 4: Add nuts and butter

Sprinkle chopped pecans or walnuts evenly over the dry cake mix.
Slowly drizzle the melted butter over the entire surface, trying to moisten as much of the cake mix as possible.
Tilt the pan gently if needed to help the butter spread, but do not mix the layers.

Step 5: Bake

Place the pan on the middle rack of the oven.
Bake for 45 to 55 minutes, until the top looks golden brown and the edges bubble slightly.
The center should feel mostly set with a slight jiggle when you nudge the pan.

Step 6: Cool and serve

Remove the Pumpkin Dump cake Recipe from the oven and place the pan on a cooling rack.
Let it cool at least 20 minutes for a warm, scoopable dessert or longer if you want cleaner slices.
Serve with whipped cream, vanilla ice cream, or a drizzle of caramel sauce.

What to Serve with Pumpkin Dump cake Recipe

Pumpkin Dump cake Recipe pairs beautifully with a big scoop of vanilla ice cream that melts into the warm, spiced layers. You can also top each serving with a generous cloud of whipped cream and a light dusting of cinnamon. Fresh fruit on the side, like sliced apples or pears, adds a nice contrast to the rich dessert. A mug of hot coffee, chai, or cocoa turns it into a cozy fall treat that feels special without extra effort.
