Shopping List
- 1 can (15 ounces) pumpkin puree (not pumpkin pie filling)
- 1 can (12 ounces) evaporated milk
- 3 large eggs
- 3/4 cup granulated sugar
- 1/4 cup brown sugar (light or dark)
- 2 teaspoons pumpkin pie spice (or see variation below)
- 1 teaspoon vanilla extract
- 1/2 teaspoon fine salt
- 1 box yellow cake mix (about 15.25 ounces)
- 3/4 cup unsalted butter, melted (plus extra for greasing the pan)
- 1/2 cup chopped pecans or walnuts (optional)
- Whipped cream or vanilla ice cream, for serving (optional but highly recommended)
Step-by-Step Instructions
- Preheat the oven: Set your oven to 350°F (175°C).
Lightly grease a 9×13-inch baking dish with butter or cooking spray.
- Make the pumpkin filling: In a large bowl, whisk together pumpkin puree, evaporated milk, eggs, granulated sugar, brown sugar, pumpkin pie spice, vanilla, and salt until smooth and well combined.
- Pour into the pan: Pour the pumpkin mixture into the prepared baking dish and smooth the top with a spatula.
- Add the cake mix: Sprinkle the dry yellow cake mix evenly over the pumpkin layer. Don’t stir.
- Add nuts (optional): If using, sprinkle chopped pecans or walnuts over the cake mix.
- Drizzle with butter: Slowly pour the melted butter evenly across the top. Try to cover as much of the dry mix as possible for even browning.
- Bake: Place the dish on the center rack and bake for 50–60 minutes, until the top is golden and the edges are bubbling.
The center should be set but slightly jiggly, like pumpkin pie.
- Cool: Let it cool on a rack for at least 20–30 minutes. This helps the layers firm up for easier slicing.
- Serve: Spoon into bowls or slice into squares. Top with whipped cream or a scoop of vanilla ice cream.
Storage Instructions
- Refrigerator: Cover the cooled cake and refrigerate for up to 4 days.
The topping will soften slightly but still tastes great.
- Freezer: Wrap tightly in plastic and foil, or store in an airtight container, for up to 2 months. Thaw overnight in the fridge and warm gently in a 300°F oven for 10–15 minutes.
- Reheating: Warm individual portions in the microwave for 20–30 seconds or in the oven at 300°F until heated through.
Health Benefits
- Pumpkin is nutrient-dense: It’s rich in beta-carotene (a precursor to vitamin A), which supports eye health and immune function.
- Good fiber content: Pumpkin puree provides fiber, which supports digestion and helps you feel full longer.
- Lower-fat swaps available: You can reduce saturated fat by using less butter or a light evaporated milk alternative.
- Antioxidant spices: Cinnamon, ginger, and nutmeg offer antioxidants and a warm flavor without extra calories.
Pitfalls to Watch Out For
- Using pumpkin pie filling: It’s already sweetened and spiced, which throws off the balance. Use plain pumpkin puree.
- Dry spots on top: If the melted butter doesn’t cover the cake mix evenly, you may get dusty patches.
Tilt the pan or use a spoon to gently distribute butter.
- Overbaking: The pumpkin layer should be set, not dry. If it’s cracking or pulling away too much from the sides, it went too long.
- Skipping the salt: A small amount of salt sharpens flavor and keeps the dessert from tasting flat.
- Cutting too soon: Let it rest so the custard layer can firm up. Serving immediately can make it soupy.
Variations You Can Try
- Spice blend swap: No pumpkin pie spice?
Use 1 1/2 teaspoons cinnamon, 1/2 teaspoon ginger, 1/4 teaspoon nutmeg, and a pinch of cloves.
- Chocolate twist: Add 1/2 cup mini chocolate chips over the cake mix before the butter for a richer, dessert-like finish.
- Pecan pie vibes: Drizzle 1/4 cup salted caramel sauce over the cake mix before baking and top with pecans.
- Dairy-free: Use full-fat coconut milk instead of evaporated milk and plant-based butter for drizzling. Check that your cake mix is dairy-free.
- Gluten-free: Swap in a gluten-free yellow cake mix. Texture stays very similar.
- Lighter version: Reduce butter to 1/2 cup and use 2/3 cup sugar total.
The topping will be slightly less crisp but still tasty.
- Spiced streusel: Mix 1/2 cup of the cake mix with 1/4 cup brown sugar, 1 teaspoon cinnamon, and 2 tablespoons melted butter; sprinkle over the top for extra crunch.
FAQ
Can I make Pumpkin Dump Cake ahead of time?
Yes. Bake it the day before, cool completely, cover, and refrigerate. Warm in a 300°F oven for 10–15 minutes before serving, or serve cold like a custard dessert.
Do I need to mix the cake mix into the pumpkin layer?
No.
The “dump” method works because the dry mix absorbs moisture from the pumpkin layer and butter as it bakes, creating a crisp, cake-like topping.
What if I don’t have evaporated milk?
You can use 1 1/2 cups half-and-half or a mix of 1 cup whole milk plus 1/2 cup heavy cream. Full-fat coconut milk also works for a dairy-free option.
How do I know it’s done baking?
The top should be golden and set, and the pumpkin layer should jiggle slightly in the center but not slosh. A toothpick won’t be reliable here, so go by appearance and the bubbly edges.
Can I use a different cake mix flavor?
Absolutely.
Spice cake, butter pecan, or white cake mix all work well. Spice cake will give extra warm notes and a deeper flavor.
Is this dessert very sweet?
It’s sweet, but balanced by the pumpkin and spice. If you prefer less sweetness, reduce the granulated sugar to 1/2 cup and use unsweetened whipped cream on top.
Can I add a crust to the bottom?
If you want more structure, press a simple graham cracker crust into the pan (1 1/2 cups crumbs + 5 tablespoons melted butter).
Par-bake for 8 minutes, then proceed with the recipe.
