Gather Your Ingredients

• canned pumpkin puree (not pie filling)
• evaporated milk
• eggs
• brown sugar
• white sugar
• cinnamon
• ginger
• cloves
• salt
• a spice or yellow cake mix from a box
• chopped pecans (or your favorite nut)
• butter (melted)

How to Make It

1. Preheat oven to 350°F (175°C) and grease a 9×13-inch baking pan.
2. In a large bowl, combine canned pumpkin puree, evaporated milk, eggs, brown sugar, white sugar, cinnamon, ginger, cloves, and salt; stir gently until just combined.
3. Pour the pumpkin mixture into the prepared pan and spread evenly.
4. Sprinkle the dry boxed cake mix evenly over the pumpkin layer.
5. Scatter chopped pecans over the top.
6. Drizzle melted butter evenly over the dry cake mix and nuts.

7. Bake in the preheated oven until the edges are bubbling and the topping is golden brown and crisp, about 50–60 minutes.

   

8. Let the cake cool until the filling sets (about 15 minutes) before slicing.

Pro Tips for Perfect Texture

1. Drizzle melted butter evenly over the dry cake mix for an even, golden-brown crust—the butter helps form that perfectly crisp topping we all crave in a pumpkin dump cake.
2. Use plain pumpkin puree rather than pumpkin pie filling so you control how sweet and spiced it gets; pie filling is already sweetened and can throw off the balance. If you want to start from scratch, roast your own pumpkin and blend it into puree.
3. Mix the pumpkin base just enough to combine ingredients without over-stirring to keep the texture light and tender inside.
4. Make sure the dry cake mix and nuts cover the pumpkin filling evenly to avoid any soggy or overly dense spots.
5. Bake until the top is golden and the center is set (for visual cues, see our easy pumpkin dump cake recipe); it’s normal for a toothpick to have moist crumbs, but don’t let wet batter stay in the middle.
6. Let the cake cool for about 15 minutes so the filling firms up—this makes it way easier to slice and serve without it falling apart.

Flavor Swaps and Add-Ins

• Try swapping the spice cake mix for yellow, butter, or even gingerbread cake mix to make the flavor your own and add a fun twist to the pumpkin dump cake.
• Switch pecans for chopped walnuts or sliced almonds if that’s what you have; all add a nice crunch and flavor.
• For a luscious, creamy filling, stir about 4 ounces of softened cream cheese into the pumpkin mixture before layering—it adds a subtle tang and smooth texture (think the cozy profile of a Chocolate Pumpkin Cheesecake Cake).
• Add 1/4 cup of maple syrup or molasses into the pumpkin batter to deepen the sweetness and bring out those classic fall flavors.
• For an extra crumbly touch, sprinkle a simple streusel topping made from brown sugar, flour, and cold butter on top of the dry cake mix before baking.

Storing and Reheating Tips

Once your pumpkin dump cake has cooled completely, cover it tightly and store it in the fridge for up to 4 days — perfect for leftovers or make-ahead dessert plans. When you’re ready to eat, warm individual slices in the microwave for about 20 to 40 seconds, or heat the whole pan in a 325°F oven for 10 to 15 minutes. If you’re worried about the topping getting too dark, tent the pan with foil while reheating. Looking to stash some for later? Wrap slices tightly and freeze for 2 to 3 months. Thaw them overnight in the fridge, then reheat. You can even put the whole unbaked cake together in the fridge a few hours ahead if needed, though baking it fresh the same day gives you the best texture.

Common Questions Answered

Q: Can I use pumpkin pie filling instead of pumpkin puree? A: I wouldn’t recommend it—pumpkin pie filling is already loaded with sugar and spices, so it can make the cake too sweet and change the texture. Stick with plain canned pumpkin for the best results and control over sweetness and spice. If you’re after classic pie flavor, try our Homemade Fresh Pumpkin Pie.

Q: Can I make this gluten-free or low-sugar? A: Absolutely! Just pick a gluten-free boxed cake mix for a gluten-free pumpkin dump cake. For low sugar, find a reduced-sugar mix and cut back on added sugars, but keep in mind this might change the cake’s texture and sweetness level a bit.

Q: What’s the secret to getting the crunchiest topping? A: Melt your butter and pour it evenly over the dry cake mix instead of dotting with cold cubes. This helps the fat soak into the top for that beautiful crispy, golden crust. Chopped nuts also add a great crunch.

Q: Is it normal if the center feels a bit moist when I check with a toothpick? A: Yes! The pumpkin part keeps the inside moist and tender. Just make sure you don’t underbake where the filling looks wet or runny—the center should hold together with moist crumbs but no raw batter.

Q: Can I halve this recipe or use a different pan size? A: You sure can. Cut ingredients in half and bake in an 8×8-inch pan—just check for doneness a little earlier since smaller pans usually bake faster. If your pan is deeper, baking times might be a bit longer, so keep an eye on it.
