Step-by-Step Instructions

Preheat and Prep
- Preheat your oven to 350°F (175°C).
- Grease a 9×13-inch baking dish with butter or non-stick spray.
Make the Pumpkin Base
- In a large mixing bowl, whisk together:
  - 1 can pumpkin puree
  - 1 can evaporated milk
  - 3 eggs
  - 1 cup granulated sugar
  - 1/2 cup brown sugar
  - 1 tsp cinnamon
  - 1/2 tsp nutmeg
  - 1/2 tsp ginger
  - 1/4 tsp cloves
- Mix until smooth and well combined.
Pour Into Baking Dish
- Pour the pumpkin mixture into the prepared baking dish.
- Use a spatula to level it out evenly.
Add the Dry Layers
- Sprinkle the dry yellow cake mix evenly over the pumpkin filling.
- Do not stir or mix in—just sprinkle evenly.
- Next, evenly sprinkle the rolled oats across the cake mix.
- Add chopped pecans on top, if using.
Drizzle with Butter
- Drizzle the melted butter evenly over the oats and pecans.
- Try to cover as much of the top as possible to help everything brown and crisp.
Bake
- Bake for 50 to 60 minutes or until the top is golden brown and a toothpick inserted near the center comes out mostly clean.
- The filling should be set and bubbling around the edges.
Cool and Serve
- Let the cake cool for at least 15 minutes before serving.
- It can be served warm, at room temperature, or even chilled the next day.

Serving and Storage Tips

- Top with whipped cream or vanilla ice cream.

- Dust with cinnamon or powdered sugar for a festive finish.

- Freeze: Wrap individual portions and freeze for up to 2 months.
- Reheat: Warm in the microwave or a 300°F oven until heated through.

Helpful Notes

Oats Matter: Use old-fashioned rolled oats for a hearty, chewy texture. Quick oats can become too mushy.
Don’t Mix Layers: Resist the urge to stir—the magic of a dump cake is the layered texture.

Customizable Add-Ins: Swap pecans for walnuts, or add dried cranberries for extra seasonal flair.
Make It Dairy-Free: Use coconut milk instead of evaporated milk and a dairy-free butter alternative.
Pumpkin Pie Spice Shortcut: You can replace the individual spices with 2 teaspoons of pumpkin pie spice.

Frequently Asked Questions

Can I use pumpkin pie filling instead of puree?
No, pumpkin pie filling is already sweetened and spiced. Stick with pure pumpkin puree.
What if I don’t have evaporated milk?
You can use half-and-half or a mixture of milk and cream.
Can I make this ahead of time?
Absolutely! This cake actually tastes better the next day as the flavors meld.

Is it supposed to be soft in the center?
Yes. The filling is custardy like pumpkin pie, but the top should be firm and golden.
Can I skip the nuts?
Of course! The pecans are optional and can be left out or replaced with a nut-free topping like granola.
