Ingredients You’ll Need
Each ingredient has a clear job in this recipe, and the short list makes shopping uncomplicated. Use pure pumpkin puree rather than pumpkin pie filling, since pie filling already contains sweeteners and spices that would change the balance.
- Pure pumpkin puree: One 15-ounce can gives the dessert its creamy pumpkin body and rich autumn color.
- Evaporated milk: The 12-fluid-ounce can adds concentrated dairy richness without making the custard watery.
- Eggs: Three large eggs help the pumpkin layer set while keeping it soft and tender.
- Granulated sugar: One cup sweetens the pumpkin mixture and complements the buttery topping.
- Pumpkin pie spice: One tablespoon gives the dessert a pronounced blend of warm seasonal spices.
- Yellow cake mix: Use one box of about 15.25 ounces, sprinkling it over the pumpkin layer while still dry.
- Butter: One cup, or two sticks, is important for moistening the cake mix and creating a rich golden crust.
- Nuts: One cup of chopped pecans or walnuts is optional but adds texture and a lightly toasted flavor.
Salted or unsalted butter works well. If using salted butter, the small amount of salt adds contrast to the sweet pumpkin and cake topping.
How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C) and lightly grease a 9-by-13-inch baking dish. Greasing helps with serving later, although the dish may also be left ungreased if preferred.
Step 2: Add the pumpkin puree, evaporated milk, eggs, sugar, and pumpkin pie spice to a large mixing bowl. Whisk until the mixture looks smooth, with no visible streaks of egg or dry spice clumps.
Step 3: Pour the pumpkin mixture into the prepared baking dish. Gently tilt the dish or use a spatula to create an even layer so the finished custard cooks at a consistent rate.
Step 4: Open the yellow cake mix and sprinkle it evenly over the entire pumpkin surface. Do not stir the cake mix into the pumpkin, because keeping the layers separate creates the signature dump-cake texture.
Step 5: Melt the butter and drizzle it slowly across the cake mix, aiming to cover as much of the surface as possible. You can also thinly slice cold butter and arrange the slices across the top, then scatter on the pecans or walnuts if using.
Step 6: Place the dish in the oven and bake for 50–60 minutes. The topping should be golden brown, and the pumpkin center should look set while retaining a slight softness rather than appearing liquid.
Step 7: Remove the cake from the oven and let it cool for at least 15–20 minutes. This short rest allows the pumpkin layer to firm up enough for serving while keeping the dessert warm and spoonable.
Step 8: Spoon portions into bowls or onto dessert plates and add whipped cream or a scoop of vanilla ice cream. Serve while warm for the strongest contrast between the buttery cake, creamy pumpkin, and cool topping.
Pro Tips for a Golden Topping
The most important detail is even coverage. Spread the dry cake mix from edge to edge, paying attention to corners, then distribute the full cup of butter across the surface.
Uncovered cake mix is the main cause of powdery spots. If you notice a few dry areas before baking, carefully add a little more butter from the prepared amount rather than leaving those patches exposed.
For the best pumpkin texture, avoid overbaking. The top should be golden and baked through, but the center can still have a gentle wobble because it will continue to set as it cools.
One tablespoon of pumpkin pie spice provides a noticeable, warmly spiced flavor. If you prefer a gentler spice profile, some versions use 2 teaspoons instead, but keep the rest of the ingredient quantities unchanged.

Serving Ideas
Serve this dessert warm after its 15–20-minute resting period. A large spoonful of lightly sweetened whipped cream melts into the warm topping, while vanilla ice cream creates a rich, creamy contrast.
Chopped pecans bring a classic autumn flavor and a pleasant crunch. Walnuts are equally good and provide a slightly more robust, earthy bite against the soft pumpkin layer.
For an attractive presentation, spoon the cake into shallow bowls so both layers are visible. Finish each serving with a small pinch of chopped nuts or a dusting of pumpkin pie spice.
This recipe is sweet and satisfying on its own, so coffee, black tea, or a glass of cold milk makes an easy beverage pairing. For another fun boxed-mix bake, see these simple cake mix donuts.
Storage and Reheating
Let leftover cake cool, then cover the baking dish tightly or transfer portions to airtight containers. Refrigerate the leftovers because the pumpkin layer contains eggs and evaporated milk.
To reheat, warm an individual serving gently until it is heated through, then add whipped cream or vanilla ice cream just before eating. The topping may soften slightly in the refrigerator, but the buttery pumpkin flavor remains delicious.
You can also enjoy leftovers chilled if you prefer a firmer, more custard-like texture. In either case, use the cake within a few days for the best quality.
Easy Variations
The classic recipe is balanced as written, but a few small changes can make it suit your table. Add the optional nuts for crunch, or leave them out for a smooth, family-friendly topping.
You can use salted or unsalted butter, and either melted butter or thinly sliced butter works. Melted butter is quick to drizzle, while thin slices are convenient when you want to avoid an extra saucepan.
For a stronger spice impression, keep the full tablespoon of pumpkin pie spice. For a softer flavor, use 2 teaspoons, as some commonly published versions do, without adding extra sugar or liquid.
