This easy baked pumpkin dessert is a pumpkin crunch cake made with a smooth pumpkin custard layer, dry yellow cake mix, chopped pecans, and melted butter. It takes just 10 to 15 minutes to assemble, bakes in a 9 x 13-inch dish for 50 to 60 minutes, and makes 12 to 16 servings.
The finished dessert has a warmly spiced, creamy pumpkin center beneath a crisp, buttery, golden topping. Serve it warm after at least 30 minutes of cooling, or chill it for especially neat slices with whipped cream or vanilla ice cream.

When you want a homemade pumpkin dessert without rolling pastry, making a complicated custard, or preparing several separate components, this recipe is a wonderful choice. The pumpkin base comes together in one bowl, while the topping needs only a box of yellow cake mix, pecans, and melted butter.
As it bakes, the layers transform into something special. The pumpkin mixture becomes soft, rich, and gently spiced, while the cake mix absorbs the butter and forms a golden crust with crisp edges and a pleasantly tender center.
This dessert is also generous enough for a holiday table, classroom gathering, or weekend potluck. Depending on how large you cut the portions, one 9 x 13-inch pan serves 12 to 16 people.
For another cozy pumpkin treat, you can pair this dessert with our soft pumpkin snickerdoodles for a dessert spread with both creamy and chewy textures.
Ingredients You’ll Need
The ingredient list is short, but each item has an important job. Pure pumpkin purée supplies the earthy pumpkin flavor and creamy base, while evaporated milk gives the custard a pleasantly rich texture without making it watery.
- Pure pumpkin purée: Use one 15-ounce can, and check the label carefully. Pumpkin pie filling already contains sugar and spices, so it will change the balance of this recipe.
- Evaporated milk: One 12-fluid-ounce can blends into the pumpkin for a smooth custard layer.
- Eggs: Three large eggs help the pumpkin layer set as the dessert bakes.
- Sugar and spices: One cup of granulated sugar, one teaspoon of cinnamon, and one teaspoon of pumpkin pie spice create a classic autumn flavor.
- Yellow cake mix: Use one box weighing about 15.25 ounces. Sprinkle it dry over the pumpkin mixture rather than stirring it in.
- Pecans: One cup of chopped pecans adds a toasted crunch. Walnuts may be substituted, or the nuts may be left out.
- Unsalted butter: One cup, or 8 ounces, melted, helps the dry cake mix bake into a crisp, buttery topping.
The full cup of sugar gives this version its traditional dessert sweetness. Since the cake mix also contains sugar, you can serve smaller portions with unsweetened whipped cream for a balanced finish.

How to Make It Step-by-Step
Step 1: Heat the oven to 350°F and grease a 9 x 13-inch baking dish with butter or nonstick cooking spray. Coating the bottom and sides helps the pumpkin layer release more easily and makes cleanup simpler.
Step 2: Add the pumpkin purée, evaporated milk, eggs, granulated sugar, cinnamon, and pumpkin pie spice to a large bowl. Whisk until the mixture looks smooth and evenly blended, scraping the sides of the bowl if needed.
Step 3: Pour the pumpkin mixture into the prepared baking dish. Gently tilt the dish or use a spatula to spread the custard into an even layer so it bakes at the same rate from edge to edge.
Step 4: Sprinkle the dry yellow cake mix over the entire pumpkin surface. Do not mix it into the pumpkin, because keeping the layers separate is what creates the signature crust and creamy base.
Step 5: Scatter the chopped pecans evenly over the cake mix. Try to distribute them from corner to corner so every serving receives some of the toasted nut topping.
Step 6: Drizzle the melted butter slowly over the whole surface, aiming for any visible dry areas. The butter should moisten as much of the cake mix as possible, although a few small dry-looking spots may remain before baking.
Step 7: Place the dish in the oven and bake for 50 to 60 minutes. The dessert is ready when the topping is golden brown and the pumpkin center is set rather than loose and liquid.
Step 8: Transfer the dish to a cooling rack and let it rest for at least 30 minutes before serving. This waiting time allows the pumpkin layer to firm, making warm portions easier to scoop and chilled portions easier to slice.
Pro Tips for the Best Pumpkin Crunch Cake
The most important technique is even distribution. A thick pile of cake mix in one area or a concentrated drizzle of butter in another can leave parts of the topping powdery, so take a moment to spread both ingredients carefully.
For the cleanest presentation, cool the dessert completely and refrigerate it before cutting. The pumpkin custard becomes firmer as it chills, and a sharp knife can then create tidy squares.
If you prefer a softer, spoonable dessert, serve it warm after the required 30-minute cooling period. If you want distinct layers and neat pieces, allow it to cool longer or refrigerate it first.
Watch the topping during the last several minutes of baking. If it becomes deeply brown before the center is set, loosely cover the dish with foil and continue baking until the pumpkin layer has finished cooking.
Chopped pecans are traditional because their buttery flavor complements the pumpkin and cake topping. Walnuts work well too, while omitting the nuts gives you a smooth, crisp-topped dessert for guests with nut allergies.
Serving Suggestions
A spoonful of whipped cream is the easiest way to finish each portion. Its light texture contrasts with the rich pumpkin custard and buttery crust without adding much preparation.
Vanilla ice cream is especially good when the dessert is warm. The cold ice cream begins to melt over the crisp topping, creating a creamy sauce that mixes with the cinnamon-scented pumpkin layer.
For a pretty autumn presentation, add a small dusting of cinnamon or a few extra toasted pecans just before serving. Keep garnishes simple so the golden topping remains the visual focus.
This dessert also works well on a buffet because it can be served warm, at room temperature, or chilled. Set out a serving spoon for soft portions or cut squares in advance after refrigerating the pan.
If you are building a relaxed brunch or fall gathering menu, consider serving a slice after a savory homemade loaf such as our easy beer bread. The bread’s hearty flavor makes the sweet pumpkin finale feel even more satisfying.
Storage and Reheating
Cover leftover pumpkin dessert and refrigerate it for food-safe storage. Chilled pieces will hold their shape well and can be served directly from the refrigerator with whipped cream.
To enjoy a warm portion, place it in a microwave-safe dish and heat it gently until warmed through. Short heating intervals help prevent the pumpkin layer from becoming overly hot while the topping softens slightly.
You can also rewarm several servings in a low oven until heated. The crust is at its crispest on the day it is baked, but careful reheating still produces a comforting, spoonable dessert.
For a complete seasonal dessert table, add a fruit-based option such as our late summer peach cake or a bright tropical treat like this pineapple banana dessert. The different fruit flavors keep the menu interesting while the pumpkin crunch cake remains the cozy centerpiece.
