There’s something about pumpkin desserts that makes fall baking feel extra special, and this Pumpkin Dump Cake might be one of the easiest ways to enjoy those cozy flavors.

It starts with a creamy pumpkin filling seasoned with warm spices, then gets topped with spice cake mix, plenty of butter, and crunchy pecans. As it bakes, the top turns golden and buttery while the pumpkin layer underneath stays soft and rich.
This is the kind of dessert I love for Thanksgiving and fall gatherings because it’s simple to put together but still feels like a treat. Serve it warm with a scoop of vanilla ice cream and a drizzle of caramel sauce, and you have the perfect combination of creamy pumpkin, crunchy pecans, and buttery cake in every bite.

- 15 oz can pumpkin puree
- 12 oz can evaporated milk
- 3 large eggs, room temperature

How to Make Pumpkin Dump Cake
1. Preheat your oven to 350°F and grease a 9×13 baking dish with cooking spray.
2. In a large bowl whisk together pumpkin, evaporated milk, eggs, brown sugar, granulated sugar, pumpkin pie spice, and vanilla extract. The mixture will be very thin. Pour this into the prepared baking dish. Sprinkle the cake mix on top evenly followed by the pecans, if using. Drizzle the melted butter over the cake mix and bake for about 55-60 minutes. The cake may wiggle in the middle a small amount still but it will set up more as it cools.
3. Allow to cool for at least 45-60 minutes before serving or it may fall apart on you.
4. Serve with a scoop of ice cream and caramel sauce for a decadent dessert.
