When I need an easy fall dessert that feels cozy without turning into a big baking project, this 3-ingredient chocolate pumpkin dump cake is one of my favorite shortcuts. It leans on a box of dry chocolate cake mix, canned pumpkin, and melted butter to create a rich, pudding-like autumn dessert with a tender cake topping. It is the kind of recipe that works perfectly on a busy weeknight, especially when you want something warm and homemade with almost no prep.
This dessert is especially good served warm with a scoop of vanilla ice cream or a spoonful of whipped cream. For an extra fall touch, pair it with hot coffee, chai, or apple cider. If you are serving it after a heavier dinner, a few fresh berries on the side can help balance the deep chocolate and pumpkin flavors.
3-Ingredient Chocolate Pumpkin Dump Cake
Servings: 8
Ingredients
1 box chocolate cake mix, dry and unbaked, about 15.25 ounces
1 can pumpkin puree, 15 ounces
1 cup unsalted butter, melted
Directions
1. Preheat the oven to 350°F and lightly grease an oven-safe ceramic roasting pan.
2. Spread the pumpkin puree evenly across the bottom of the prepared pan.
3. Sprinkle the dry chocolate cake mix evenly over the pumpkin puree, covering it from edge to edge without stirring.
4. Drizzle the melted butter as evenly as possible over the top so most of the cake mix is moistened.
5. Bake for 40 to 45 minutes, until the top looks set and slightly crisp around the edges while the bottom stays soft and rich.
6. Let the dessert rest for 10 minutes before scooping and serving warm.
Variations & Tips
Add warm spice: If you do not mind going beyond the strict 3-ingredient version, a teaspoon of pumpkin pie spice or cinnamon mixed into the pumpkin puree gives the dessert an even cozier fall flavor.
Use yellow cake mix instead: For a more classic pumpkin dump cake feel, swap the chocolate cake mix for yellow or spice cake mix. The texture stays similar, but the flavor becomes lighter and more traditional for autumn gatherings.
Cover dry patches: If you see a few dry spots of cake mix before baking, drizzle a little more melted butter over those areas. Even coverage helps the topping bake up more evenly.
Make serving easy: This dessert is softer than a traditional cake, so it is best scooped with a large spoon instead of sliced. Letting it rest briefly after baking helps it hold together better.
