When you need an easy fall-style dessert with almost no prep, this oven baked pumpkin dump cake is hard to beat. It leans on pantry staples—canned pumpkin puree, sweetened condensed milk, cake mix, and butter—to create a soft pumpkin base with a buttery cake-like topping, all with very little measuring or fuss. Recipes in the dump-cake family became popular for their convenience, and this version brings that same practical spirit to pumpkin season.
Serve warm squares on their own or pair them with whipped cream, a scoop of vanilla ice cream, or a drizzle of caramel sauce. For a simple dessert spread, it goes nicely with hot coffee, chai, or cold milk, and if you are setting it out for a holiday meal, fresh apple slices or spiced pears make a nice contrast to its rich sweetness.
Oven Baked 4-Ingredient Pumpkin Dump Cake
Servings: 10
Ingredients
1 (15-ounce) can pumpkin puree
1 (14-ounce) can sweetened condensed milk
1 (15.25-ounce) box spice cake mix
1 cup butter, melted
Directions
1. Preheat the oven to 350°F and lightly grease a 9x13-inch glass casserole dish.
2. In the casserole dish or a mixing bowl, whisk the pumpkin puree and sweetened condensed milk together until completely smooth and evenly combined.
3. Spread the pumpkin mixture into an even layer, then sprinkle the dry spice cake mix evenly over the top from edge to edge.
4. Drizzle the melted butter all over the cake mix, covering every dry patch so no powder remains visible.
5. Bake for 50 to 60 minutes, until the top is golden and the center barely jiggles.
6. Let the dish rest for 30 minutes before serving so the filling can set and the slices hold together more neatly.
Variations & Tips
Use yellow cake mix: If that is what you have on hand, yellow cake mix works well here too. For a warmer pumpkin-spice flavor, you can stir 1 to 2 teaspoons pumpkin pie spice into the dry mix before sprinkling it over the filling.
Butter coverage matters: The biggest key to a good dump cake topping is making sure the melted butter reaches all the dry mix. If you see dusty spots before baking, add a little more melted butter to those areas so the top bakes up evenly instead of leaving floury patches.
Let it rest before cutting: This dessert looks very soft right out of the oven, but the 30-minute rest helps the pumpkin layer settle. If you want especially tidy portions, let it cool a bit longer and serve it just warm rather than hot.
Dress it up for serving: A spoonful of whipped cream, a dusting of cinnamon, or a small scoop of vanilla ice cream turns this into an easy company-style dessert. Chopped toasted pecans are also a nice addition if you want a little crunch.
