This easy pumpkin dump cake comes together with just 10 minutes of prep time. A smooth pumpkin filling made with purée, evaporated milk, eggs, and warm pumpkin pie spices forms the base, topped with dry yellow cake mix and melted butter that creates a golden, buttery crust. Optional pecans add crunch. Bake until golden and serve warm with whipped cream or ice cream for the ultimate cozy autumn treat.
The first time I made this, I honestly thought something had gone wrong in the oven. The cake mix sits on top like this dry, dusty layer, and you're supposed to just pour melted butter over it and trust the process. But forty-five minutes later, that same dry mix had transformed into this golden, buttery crust with pockets of crunch and pockets of soft pillowy cake. My roommate walked into the kitchen and asked what bakery smell was coming from our apartment.
I brought this to a Friendsgiving potluck last November, right when my hosting anxiety was at its peak. The dish came back empty, and three people separately messaged me for the recipe that evening. One friend confessed she'd gone back for seconds before dinner even started. Now it's the only thing I'm asked to bring to autumn gatherings, and I've stopped fighting it.
Ingredients
- Pumpkin purée: Use pure pumpkin purée, not pumpkin pie filling with the spices already added. Trust me, I learned this difference the hard way once.
- Evaporated milk: This is what gives the filling that rich, creamy texture without being too heavy. Regular milk makes it too loose.
- Yellow cake mix: Keep it dry. Do not prepare the cake mix according to the box directions. The magic happens because it's dry.
- Unsalted butter: Melt it completely but try to drizzle it as evenly as possible. Some spots will get more butter and become extra crispy.
- Pecans: Totally optional but I highly recommend them. The toastiness they develop in the oven is worth it.
Instructions
- Get your oven ready:
- Preheat to 350°F and grease a 9x13 baking dish. I use butter, but cooking spray works fine too.
- Whisk the filling:
- In a large bowl, combine the pumpkin purée, evaporated milk, eggs, both sugars, pumpkin pie spice, salt, and vanilla. Whisk until everything is smooth and incorporated. Take your time here.
- Layer it up:
- Pour that gorgeous orange pumpkin mixture into your prepared dish. Spread it into an even layer.
- Add the magic topping:
- Sprinkle the entire dry cake mix over the pumpkin layer. Yes, it looks wrong. Just keep going. Then drizzle the melted butter all over the cake mix. Try to cover as much surface area as possible.
- Add crunch and bake:
- Sprinkle pecans on top if you're using them. Bake for 45 to 50 minutes. The top should be golden brown and gorgeous.
- The hardest part:
- Let it cool for at least 20 minutes. The filling needs time to set up. Serve it warm with whipped cream or vanilla ice cream.
Last week my daughter asked if we could have breakfast cake. That's what she calls this now. I made it while she was getting ready for school, and the whole house smelled like autumn baking by the time she came downstairs. She ate two pieces before the bus came, and I'm not even mad about it.
Making It Your Own
Sometimes I swap the pecans for walnuts, depending on what's in the pantry. I've also added a handful of white chocolate chips to the topping before baking, which creates these little pools of sweetness throughout. Keep an eye on it though, because the sugar in the chips can brown faster than you'd expect.
Storage and Leftovers
This is honestly best eaten within two days, which has never been a problem in my house. Store it covered in the refrigerator, but bring it to room temperature before serving. The texture gets even better on the second day as the flavors settle. I've been known to eat a piece cold for breakfast, straight from the fridge.
Serving Ideas
Warm is definitely the way to go, but room temperature works in a pinch. A dollop of freshly whipped cream is never a mistake. My husband prefers his with a scoop of vanilla bean ice cream, letting it melt slightly into the warm pumpkin layer. Either way, it's the kind of dessert that makes people close their eyes and say nothing for a minute.
- Try it with a cup of strong coffee in the afternoon
- It's perfect alongside vanilla ice cream that's starting to soften
- The flavors actually improve slightly if you make it a day ahead
There's something so satisfying about a recipe that asks so little of you but gives back so much. This is the one I make when I want people to feel loved and taken care of, without spending all day in the kitchen.
Recipe Questions & Answers
- → What makes this a dump cake?
-
The dump cake method involves pouring the pumpkin filling mixture into a baking dish, then sprinkling dry cake mix over it and drizzling with melted butter. No mixing bowl is needed for the topping—everything layers directly in the pan for effortless preparation.
- → Can I use fresh pumpkin instead of canned?
-
Yes, you can use fresh pumpkin purée. Roast or boil a sugar pumpkin until tender, then purée until smooth. Use about 1¾ cups of fresh purée to equal one 15-ounce can. Make sure the purée is well-drained to avoid excess moisture.
- → How do I know when it's done baking?
-
The cake is ready when the top is golden brown and a toothpick inserted into the center comes out mostly clean—some moist crumbs are fine since the pumpkin layer remains slightly soft. The butter should be fully absorbed and the cake mix should look set, typically after 45–50 minutes at 350°F.
- → Can I make this dairy-free?
-
Absolutely. Substitute the evaporated milk with a dairy-free alternative like coconut milk or almond milk, and use plant-based butter sticks instead of regular butter. The texture and flavor remain delicious, and it's perfect for those with dairy restrictions.
- → How should I store leftovers?
-
Cover the baking dish tightly with foil or transfer leftovers to an airtight container. Refrigerate for up to 2 days. Reheat individual portions in the microwave for 20–30 seconds or serve at room temperature. The cake may become slightly more dense after refrigeration but still tastes wonderful.
- → What toppings work well with this?
-
Whipped cream or vanilla ice cream are classic choices that complement the warm spices. For extra indulgence, try a drizzle of caramel sauce, a dusting of powdered sugar, or a scoop of cinnamon ice cream. The contrast between the warm, spiced pumpkin and cold, creamy topping is irresistible.
