Pumpkin Dump cake Recipe hits that sweet spot between low effort and high payoff, and I bake it every fall when I want a cozy dessert without babysitting the oven. You stir the pumpkin filling, “dump” on a cake mix, drizzle butter, and let the oven do the rest. I first made this after a marathon pumpkin patch day, and it basically saved dessert with zero stress. If you love pumpkin pie and crumbly cake in one bite, this easy pumpkin dump cake recipe will become your go-to.
Why You Should Try Pumpkin Dump Cake Recipe
I reach for this when guests text “on our way” and I still want a warm, homemade dessert. The texture hits like pumpkin pie on the bottom and crisp buttery crumble on top. You get reliable, bakery-level flavor with pantry staples like canned pumpkin, yellow cake mix, and butter. You also slice it cleanly after it cools, so it travels well to potlucks and Friendsgiving.
Ingredients You’ll Need
- 1 can (15 ounces) pumpkin puree
- 1 can (12 ounces) evaporated milk
- 3 large eggs
- 3/4 cup granulated sugar
- 1/4 cup packed brown sugar
- 2 teaspoons pumpkin pie spice
- 1/2 teaspoon fine sea salt
- 1 teaspoon vanilla extract
- 1 box (15.25 ounces) yellow or spice cake mix
- 3/4–1 cup unsalted butter, melted (use enough to wet all dry spots)
- 1/2–3/4 cup chopped pecans (optional)
How to Make Pumpkin Dump Cake
- Prep: Heat the oven to 350°F (175°C). Grease a 9×13-inch pan or line it with a parchment sling.
- Mix the pumpkin layer: Whisk pumpkin, evaporated milk, eggs, both sugars, pumpkin pie spice, salt, and vanilla until smooth.
- Fill the pan: Pour the pumpkin mixture into the prepared pan and smooth the top.
- Add the “dump” layer: Sprinkle the dry cake mix evenly over the pumpkin layer.
- Add crunch: Scatter pecans over the cake mix if you like.
- Butter blanket: Slowly drizzle melted butter over the entire surface, covering every area of dry mix.
- Bake: Bake for 50–60 minutes, until the top turns golden and the center barely jiggles.
- Cool and serve: Let the cake cool for 20–30 minutes so the pumpkin layer sets, then slice and serve warm, room temp, or chilled.
Baking Tips
- I drizzle the butter in a crosshatch pattern to cover the cake mix evenly.
- I line the pan with parchment for ultra-neat slices and stress-free cleanup.
- I test doneness by looking for a set edge, a golden top, and a slight jiggle in the center.
- I chill leftovers overnight because the spices deepen and the texture firms up beautifully.
- I use 1 cup butter when I want a thicker, crisper crumble and 3/4 cup when I want a lighter top.
Serving Ideas for Pumpkin Dump Cake
- Spoon on whipped cream, vanilla ice cream, or cinnamon ice cream.
- Drizzle warm caramel or maple syrup for extra cozy vibes.
- Dust with powdered sugar and a pinch of cinnamon for a simple finish.
- Pair slices with hot coffee, chai, or apple cider for the perfect fall dessert moment.
- Top with toasted pepitas or crushed gingersnaps for crunch.
Substitutions & Variations
Cake mix: Use spice cake mix for extra fall flavor or yellow cake mix for a classic vanilla crumble.
Dairy-free: Swap evaporated milk with full-fat coconut milk and butter with vegan butter.
Gluten-free: Use a gluten-free yellow or spice cake mix; the texture still turns out great.
Nut-free: Skip pecans or replace them with pepitas for crunch.
Extra cozy: Add 1/2 cup butterscotch chips or white chocolate chips over the cake mix before the butter.
Egg-free option: Replace the eggs with 1/2 cup unsweetened applesauce plus 2 tablespoons cornstarch for structure.
Make-Ahead and Storage Tips
This pumpkin dump cake reheats so well that I call it my weeklong fall dessert plan.
Make-Ahead: Mix the pumpkin filling up to 24 hours ahead, cover, and refrigerate. When you want to bake, pour it into the pan, add the cake mix and butter, and bake as directed. You can also bake the cake fully, cool it, and serve it the next day for deeper spice flavor.
To Refrigerate: Store cooled cake covered in the fridge for up to 5 days. Keep the container slightly vented for the first hour to prevent steam from softening the crumble.
Freezing: Freeze fully cooled slices tightly wrapped (or in airtight containers) for up to 3 months. Label the date so you keep rotation easy.
To Reheat: Warm slices in a 325–350°F oven or air fryer for 8–12 minutes to re-crisp the top, or microwave in 20–30 second bursts until heated through.
Mistakes to Avoid
- Use pure pumpkin puree and skip pumpkin pie filling; that can over-sweeten and throw off the spices.
- Don’t stir the cake mix into the pumpkin layer; you want a distinct crumble on top.
- Cover every dry patch of cake mix with melted butter; dry spots stay floury.
- Let the cake cool at least 20–30 minutes before slicing; the pumpkin layer needs time to set.
- Use a 9×13-inch metal or ceramic pan; smaller pans can underbake the center and overbrown the edges.
- Don’t skimp on salt and spice; a pinch of salt and enough pumpkin pie spice make the flavor pop.
