Easy Pumpkin Dump Cake: Go-To Fall Dessert

Jump to Recipe·Print Recipe·Leave a Review

Easy pumpkin dump cake has a softly set pumpkin custard underneath a buttery, crisp cake-mix topping. It uses familiar pantry ingredients and a 9-by-13-inch pan, making it practical for potlucks, holiday dinners, or any time you need 12 servings without rolling pie dough.

Despite the name, the pumpkin layer is mixed before it goes into the dish. The “dump” technique applies to the topping: dry cake mix is scattered over the custard and covered with melted butter without stirring. Keeping those layers separate creates the intended contrast.

Table of Contents

What you need

Pumpkin base: One 15-ounce can of pure pumpkin puree, evaporated milk, granulated and brown sugar, two eggs, pumpkin pie spice, and vanilla.
Golden topping: One box of dry yellow cake mix and one cup of melted unsalted butter.
Optional crunch: Chopped pecans add texture but can be omitted for a nut-free version.

How to make pumpkin dump cake

Heat the oven to 350°F (175°C) and grease a 9-by-13-inch baking dish. Whisk the pumpkin puree, evaporated milk, both sugars, eggs, pumpkin pie spice, and vanilla until smooth. Spread the mixture evenly in the pan.

Sprinkle the dry cake mix over the entire surface. Do not stir. Drizzle melted butter slowly from edge to edge, covering as much of the powder as possible, then add pecans if using. Bake for 50–60 minutes. The edges should be set, the top golden, and the center may retain a slight wobble but should not look liquid.

Prevent dry patches

Large uncovered areas of cake mix stay powdery, so distribute both the mix and butter carefully. If needed, use the back of a spoon to direct a little melted butter toward a dry spot without mixing it into the pumpkin. Let the dessert stand 15–20 minutes after baking so the custard firms enough to scoop cleanly.

Serving and storage

Serve warm, at room temperature, or chilled, with lightly whipped cream if desired. Refrigerate leftovers in an airtight container within two hours and use within 3–4 days. For another fall option, compare this recipe with pumpkin pie dump cake, or bake cranberry orange bread for a sliceable treat.

FAQs

Can I use pumpkin pie filling instead of pumpkin puree in Easy Pumpkin Dump Cake?

No, it is highly recommended to use 100% pure pumpkin puree, not pumpkin pie filling. Pumpkin pie filling is already sweetened and spiced, which would make your Easy Pumpkin Dump Cake overly sweet and potentially alter the texture and spice balance significantly.

How do I know when my Easy Pumpkin Dump Cake is done baking?

Your Easy Pumpkin Dump Cake is ready when the top is golden brown and a knife inserted into the center of the pumpkin layer comes out mostly clean. The edges should be set, and the center may have a slight, gentle jiggle. Baking typically takes 50-60 minutes.

Can I make this Easy Pumpkin Dump Cake ahead of time?

Yes, Easy Pumpkin Dump Cake can be made ahead of time. It stores well in an airtight container in the refrigerator for 3-4 days. You can reheat individual servings gently in the microwave or oven, or serve it at room temperature.

What are some common variations for Easy Pumpkin Dump Cake?

Popular variations include adding chocolate chips, a cream cheese layer, or a caramel swirl to the pumpkin mixture. You can also experiment with different nuts for the topping, like walnuts or almonds, or use a spice cake mix instead of yellow for an intensified fall flavor.

This incredibly simple and comforting dessert features a creamy, spiced pumpkin base topped with a buttery, crisp cake crumble, perfect for any fall occasion.

Total Time: 1 hour 15 minutes
Yield: 12 servings

Instructions

Step 1: Begin by preheating your oven to 350°F (175°C). Then, lightly grease a 9×13-inch baking dish.
Step 2: In a large mixing bowl, combine your 100% canned pumpkin puree with evaporated milk, granulated sugar, light brown sugar, eggs, pumpkin pie spice, and pure vanilla extract. Whisk all ingredients until thoroughly combined and smooth.
Step 3: Carefully pour the pumpkin mixture evenly into your prepared 9×13-inch baking dish. Use a spatula to gently spread it out, ensuring a uniform layer.
Step 4: Evenly sprinkle the entire contents of the dry yellow cake mix over the pumpkin layer. Vital: do NOT mix it in! The goal is a uniform, dry layer over the wet pumpkin mixture, covering every part.
Step 5: Gently drizzle the melted unsalted butter evenly over the dry cake mix. Resist the urge to stir! The butter will seep into the cake mix as it bakes, working its magic to create that wonderful, buttery, and slightly crunchy crust. If you notice any dry spots, gently nudge the butter to cover them, ensuring even caramelization and texture.
Step 6: If you’re a fan of extra crunch and nutty depth, sprinkle chopped pecans evenly over the butter and cake mix layer. This addition is optional but adds fantastic textural contrast and lovely autumnal flavor.
Step 7: Place your baking dish into the preheated oven. Bake for approximately 50-60 minutes, or until the top is golden brown and a knife inserted into the center comes out mostly clean. A little moistness from the pumpkin layer is fine, but it should not be liquid. The edges should be set, and the center might have a slight jiggle.
Step 8: Once baked, remove the Easy Pumpkin Dump Cake from the oven and let it cool for at least 15-20 minutes before serving. This cooling time allows the cake to set properly, making it easier to serve. It’s delicious warm, but also fantastic at room temperature.

Notes

For best results and to keep your cake fresh and moist, store leftovers in an airtight container in the refrigerator for up to 3-4 days. For bolder flavor, enhance the pumpkin mixture with extra spices or use a spice cake mix. Experiment with chocolate chips or a caramel swirl for variations.

Unsaturated Fat: 7.5g (Note: Original schema has ‘unsaturatedFatContent’ but the table had ‘Unsaturated Fat’, extracted as is from table content for consistency, though ‘Unsaturated Fat’ should generally be split into poly/mono. Sticking to schema output.) Correction: I should explicitly extract based on the *schema property names*. So, ‘fatContent’ will be 18g, ‘saturatedFatContent’ 10g, ‘unsaturatedFatContent’ 7.5g. The ‘Trans Fat’ from the table will be ‘transFatContent’. ‘Fiber’ will be ‘fiberContent’, ‘Sugar’ to ‘sugarContent’. The original prompt table has ‘Unsaturated Fat’ as 7.5g and ‘Trans Fat’ as 0.5g. I will use these. Re-evaluating nutrition keys vs table provided: Fat (18g) -> fatContent, Saturated Fat (10g) -> saturatedFatContent, Unsaturated Fat (7.5g) -> unsaturatedFatContent, Trans Fat (0.5g) -> transFatContent. All good. Let me correct the thought process of extracting it directly from the table, not by copying values from the comment into the generated output. The output will be clean JSON values. Re-extracting from table now to ensure perfect match to schema properties). Re-evaluating from provided table: Fat (18g), Saturated Fat (10g), Unsaturated Fat (7.5g), Trans Fat (0.5g). This is correct for the output.
