Ingredients You Need

Wet & Pumpkin Layer

1 can (15 ounces) pumpkin puree
- Use 100% pure pumpkin, not pumpkin pie mix. Libby’s or store brand both work well.
1 can (12 ounces) evaporated milk
- Gives a custardy, pumpkin pie style texture.
3 large eggs
3/4 cup granulated sugar
1/2 cup light brown sugar, packed
2 teaspoons pumpkin pie spice
- Or use 1 1/2 teaspoons cinnamon, 1/4 teaspoon nutmeg, 1/4 teaspoon ginger, and a tiny pinch of cloves.
1 teaspoon vanilla extract
1/2 teaspoon fine sea salt or table salt

Dry & Topping Layer

1 box yellow cake mix (about 15.25 ounces)
- Yellow cake mix gives a buttery, classic flavor. Spice cake mix works if you want extra spice.
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)
- Adds crunch and a nutty flavor. Skip if you need a nut free dessert.

Optional Garnishes

Whipped cream or whipped topping
Vanilla ice cream
Caramel sauce
Extra cinnamon for sprinkling

Pantry Shortcuts & Substitutions

Use canned pumpkin puree and boxed cake mix to keep this Pumpkin Dump cake Recipe weeknight friendly.
Swap evaporated milk with half-and-half in a pinch, though the texture turns slightly richer.
Replace brown sugar with all white sugar if needed, but brown sugar adds deeper flavor.
Use spice cake mix instead of yellow cake mix if you love strong pumpkin spice flavor.

9×13 inch baking pan (glass or metal)
Large mixing bowl

Tips & Mistakes

Grease the pan well so the pumpkin layer releases easily and the corners do not stick.
Whisk the pumpkin mixture until smooth so you avoid streaks of egg or spice.
Sprinkle the dry cake mix evenly over the pumpkin layer so you avoid dry flour pockets.
Drizzle the melted butter evenly over the cake mix instead of pouring in one spot.
Do not stir the layers together in the pan, or you lose that cobbler style topping.
Bake until the top looks deep golden and feels set in the center, not jiggly.
Let the Pumpkin Dump cake Recipe cool at least 20 to 30 minutes so the pumpkin layer thickens.
Chill leftovers within 2 hours so the custard style base stays safe and tasty.

How to Make Pumpkin Dump cake Recipe

Step 1: Prep the Pan and Oven

Preheat your oven to 350°F. Grease a 9×13 inch pan with butter or nonstick spray, and coat the corners well. Set the pan aside while you mix the pumpkin layer.

Step 2: Mix the Pumpkin Custard Base

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 even in color. Pour this pumpkin mixture into the greased pan and spread it into an even layer.

Step 3: Add the Cake Mix Layer

Open the box of yellow cake mix and sprinkle the dry mix evenly over the pumpkin layer. Cover the entire surface and break up any clumps with your fingers. Do not stir; keep the pumpkin layer on the bottom and the dry mix on top.

Step 4: Add Butter and Nuts

Melt the butter until fully liquid, then let it cool for a minute so it does not scorch the cake mix. Drizzle the melted butter slowly and evenly over the entire surface of the cake mix. Sprinkle chopped pecans or walnuts over the top if you use them.

Step 5: Bake

Place the pan on the center rack of the oven. Bake at 350°F for 45 to 55 minutes, until the top looks deep golden brown and the edges bubble slightly. Check the center; it should feel set and not slosh when you gently shake the pan.

Step 6: Cool and Set

Remove the Pumpkin Dump cake Recipe from the oven and place the pan on a cooling rack. Let it cool at least 20 to 30 minutes so the pumpkin layer thickens and slices hold their shape. Serve warm, at room temperature, or chilled, depending on your texture preference.

Variations I've Tried

I swap the yellow cake mix with spice cake mix when I want extra warm spice flavor that tastes closer to pumpkin bread. I also tried a butter pecan cake mix, which added a toasty, nutty flavor that worked great for holiday dinners. Sometimes I swirl 4 ounces of softened cream cheese into the pumpkin layer for a richer, cheesecake style vibe.

I sprinkle mini chocolate chips over the cake mix layer when I bake this for kids who love chocolate with pumpkin. I also skip nuts and add crushed graham crackers or crushed gingersnaps on top for extra crunch. When I want a lighter feel, I reduce the butter to 1/2 cup and accept a slightly less rich topping that still tastes great.

How to Serve Pumpkin Dump cake Recipe

Serve Pumpkin Dump cake Recipe warm with a big spoonful of whipped cream or a scoop of vanilla ice cream. Add a light drizzle of caramel sauce and a pinch of cinnamon for a bakery style finish. I like to cut neat squares for parties and scoop rustic servings straight from the pan for family nights.

This dessert works well for potlucks, holiday dinners, or casual weeknight treats. Pair it with hot coffee, chai, or a mug of hot chocolate for a cozy fall dessert plate.

How to store

Store leftovers covered in the fridge for up to 4 days; the pumpkin custard layer stays creamy and the topping keeps some texture.
Chill the pan uncovered for about 30 minutes first, then cover with foil or a lid so condensation does not drip on top.
Freeze individual portions in airtight containers for up to 2 months; thaw overnight in the fridge before serving.
Reheat single servings in the microwave for 20 to 30 seconds or warm larger portions in a 300°F oven for 10 to 15 minutes until heated through.
