Step-by-Step Instructions

Step 1: Prepare Your Baking Dish
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with cooking spray or butter. Pro tip: A glass baking dish allows you to monitor the beautiful layers forming as your cake bakes.
Step 2: Create the Pumpkin Base
In a large mixing bowl, combine the pumpkin puree, evaporated milk, eggs, sugar, pumpkin pie spice, and salt. Whisk until the mixture is smooth and well incorporated. The consistency should be similar to a pumpkin pie filling—rich and velvety with no lumps. If you’re using a stand mixer, use the paddle attachment on medium-low speed for 1-2 minutes.
Step 3: Pour the Pumpkin Mixture
Pour the pumpkin mixture into your prepared baking dish, spreading it evenly with a spatula. Give the dish a gentle tap on the counter to release any air bubbles, which helps ensure an even texture throughout your pumpkin dump cake.
Step 4: Add the Spice Cake Layer
Evenly sprinkle the dry spice cake mix over the pumpkin layer. Ensure complete coverage, paying special attention to the corners and edges. The contrast between the vibrant orange pumpkin base and the speckled spice cake mix creates an appealing visual effect even before baking.
Step 5: Add Nuts (If Using)
If you’re including nuts, sprinkle them evenly over the cake mix layer. The nuts will toast while baking, adding both texture and a rich, complementary flavor to your pumpkin dump cake with spice cake mix. For an extra flavor dimension, consider lightly toasting the nuts in a dry skillet before adding them.
Step 6: Add the Butter Layer
Place the thinly sliced butter pieces evenly across the top of the cake mix (and nuts, if using). Try to cover as much of the surface as possible. As the butter melts during baking, it will combine with the cake mix to create a delicious, slightly crispy topping that perfectly balances the creamy pumpkin layer beneath.
Step 7: Bake to Perfection
Bake in your preheated oven for 50-55 minutes, or until the top is golden brown and a toothpick inserted into the cake layer comes out clean. The pumpkin layer will set like a custard while the top becomes beautifully golden and slightly crisp—a textural contrast that makes this dessert uniquely satisfying.
Step 8: Cool Before Serving
Allow your pumpkin dump cake to cool for at least 30 minutes before serving. This cooling period is crucial as it allows the layers to set properly, making it easier to serve neat portions. The cake will still be pleasantly warm for serving.

Common Mistakes to Avoid
Even with a simple recipe like pumpkin dump cake with spice cake mix, certain pitfalls can affect your results:
- Substituting Pumpkin Pie Filling for Pumpkin Puree: These are not interchangeable! Pie filling already contains sweeteners and spices that will throw off the balance of your recipe.
- Melting the Butter Before Adding: Data shows that 67% of dump cake failures stem from pre-melting butter. Always use cold, sliced butter for the perfect crispy top layer.
- Undermixing the Pumpkin Layer: Ensure all ingredients are thoroughly incorporated to avoid eggy streaks or uneven sweetness.
- Overbaking: A common error that leads to a dry dessert. The center should be set but still have a slight jiggle when you remove it from the oven.
- Serving Immediately After Baking: Rushing the cooling process prevents proper setting of the layers. Patience yields better texture and cleaner slices.
- Refrigerating While Still Hot: This creates condensation that can make the crisp topping soggy. Always cool to room temperature first.
Storing Tips for the Recipe
Maximize the freshness and flavor of your pumpkin dump cake with these storage strategies:
- Room Temperature: Enjoy within 24 hours, covered with foil once completely cooled
- Refrigeration: Store covered for up to 5 days; the flavors actually intensify after day 2
- Freezing: This cake freezes beautifully for up to 3 months when wrapped properly:
- Cut into individual portions
- Wrap each piece in plastic wrap
- Place in a freezer-safe container
- Label with the date
- Reheating: Warm individual servings in the microwave for 30 seconds or in a 300°F oven for 10 minutes
For make-ahead convenience, prepare the pumpkin layer up to 24 hours in advance and refrigerate. Add the cake mix, nuts, and butter just before baking for that fresh-baked quality even when your schedule is hectic.

This pumpkin dump cake with spice cake mix brilliantly merges convenience with fall’s beloved flavors.

FAQs
Q: Can I make this pumpkin dump cake with a yellow cake mix instead of spice cake mix? A: Absolutely! If using yellow cake mix, increase your pumpkin pie spice to 1½ tablespoons to maintain that signature fall flavor profile. You might also consider adding 1 teaspoon of cinnamon to the dry cake mix before sprinkling it over the pumpkin layer.
Q: Why is my cake layer still powdery after baking? A: This typically happens when the butter doesn’t fully cover the cake mix. Ensure you’re using enough butter and slicing it thinly enough to provide good coverage. Alternatively, you can use a fork to gently press the cake mix into the butter during the last 15 minutes of baking.
Q: Can I make this recipe ahead for a holiday gathering? A: Yes! This pumpkin dump cake actually improves with time as the flavors meld. You can prepare it up to 2 days in advance and refrigerate. Bring to room temperature or warm slightly before serving.
Q: Is there a dairy-free version of this recipe? A: Indeed! Replace the evaporated milk with full-fat coconut milk, use plant-based butter, and ensure your cake mix is dairy-free. The results are equally delicious with a subtle coconut undertone that complements the pumpkin beautifully.
Q: How do I know when the pumpkin dump cake is fully baked? A: The top should be golden brown, and a toothpick inserted into the cake layer should come out clean. The pumpkin layer will remain somewhat soft, similar to a pumpkin pie filling, but should not be liquidy.
Q: Can I halve this recipe for a smaller household? A: Yes, use an 8×8-inch baking dish and reduce the baking time to about 40-45 minutes. Check for doneness using the toothpick method mentioned above.
