What Is a Dump Cake?

The term “dump cake” might not sound glamorous, but the idea is genius. You simply ‘dump’ a few pantry staples into a baking dish, layer them, and pop it into the oven. It’s a hybrid between a cobbler and a cake, known for its ease and rustic charm.

For this particular version, we’re giving it a delightful autumn twist with pure pumpkin puree, warm spices like cinnamon and nutmeg, and a topping of buttery oats for added crunch and texture.

Ingredients You’ll Need

Before we dive into the full recipe, here’s a look at what goes into making this delicious seasonal dump cake:

1 can (15 oz) pumpkin puree – Not pumpkin pie filling!
1 can (12 oz) evaporated milk
3 large eggs
1 cup granulated sugar
1 tsp ground cinnamon
1/2 tsp ground nutmeg
1/4 tsp salt
1 box yellow cake mix
1 cup quick oats
3/4 cup melted butter
Optional toppings: whipped cream, caramel drizzle, chopped pecans

How to Make Pumpkin Oatmeal Dump Cake

Step 1: Preheat and Prepare

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with non-stick cooking spray.

Step 2: Make the Pumpkin Base

In the baking dish, whisk together the pumpkin puree, evaporated milk, eggs, sugar, cinnamon, nutmeg, and salt until smooth. You can mix this directly in the pan to reduce dishes.

Step 3: Add Cake Mix and Oats

Evenly sprinkle the dry yellow cake mix over the pumpkin layer. Then, sprinkle the oats on top for extra texture and flavor.

Step 4: Pour on the Butter

Drizzle the melted butter evenly over the entire surface. This helps the oats and cake mix form a crisp, golden topping.

Step 5: Bake and Cool

Bake for 50–60 minutes, or until the center is set and the top is golden brown. Let it cool for at least 15 minutes before serving.
