Ingredients with Quantities
To create this fall-inspired dessert, you’ll need a few simple pantry staples.
Main Ingredients
- 1 (15 oz) can pumpkin puree – Make sure it’s pure pumpkin, not pumpkin pie filling.
- ½ cup brown sugar – Adds a deep caramel-like sweetness that pairs perfectly with pumpkin.
- 1 teaspoon pumpkin pie spice – You can substitute with ½ teaspoon cinnamon, ¼ teaspoon nutmeg, and ¼ teaspoon ginger.
- 1 box yellow cake mix (≈ 15.25 oz) – This is the magic ingredient that creates a light, crumbly topping.
- 1 cup old-fashioned rolled oats – Adds a toasty, chewy texture on top.
- ¾ cup melted butter – Brings richness and helps brown the topping.
Optional Garnishes
- Whipped cream or vanilla ice cream (for serving)
- Caramel sauce drizzle (optional but heavenly)
- Chopped pecans or walnuts (for extra crunch)
Equipment You’ll Need
- 9×13-inch baking dish
- Mixing bowl
- Spatula or spoon
- Measuring cups and spoons
- Nonstick cooking spray or butter for greasing
Directions and Preparation Method
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). Grease your 9×13-inch baking dish generously with nonstick spray or butter to prevent sticking and ensure easy cleanup.
Step 2: Prepare the Pumpkin Mixture
In a large mixing bowl, combine the following:
- Pumpkin puree
- Brown sugar
- Pumpkin pie spice
Stir until the mixture becomes smooth and creamy. This will be your flavorful pumpkin base layer — sweet, spiced, and perfectly moist.
Step 3: Spread the Pumpkin Layer
Pour the pumpkin mixture into the greased baking dish. Using a spatula, spread it evenly to cover the entire bottom of the dish. This layer will bake into a creamy, custard-like base.
Step 4: Add the Cake Mix
Sprinkle the dry yellow cake mix evenly over the pumpkin layer. Don’t mix or press it down. The dry mix will combine with the butter during baking, forming a crumbly, golden top crust.
Step 5: Add the Oats
Next, sprinkle 1 cup of rolled oats evenly on top of the cake mix. The oats will toast beautifully, giving a crisp and slightly nutty finish.
Step 6: Pour the Melted Butter
Slowly drizzle the ¾ cup melted butter over the entire surface. Be sure to coat as much of the dry mix as possible to achieve even browning. The butter acts as the glue that binds the oats and cake mix into a crispy topping.
Step 7: Bake the Cake
Place the dish in the preheated oven and bake for 40 to 45 minutes, or until the top is golden brown and the edges are bubbling. The aroma of pumpkin and spice will fill your kitchen — that’s when you know it’s nearly done!
Step 8: Cool Before Serving
Once baked, let the cake cool for at least 10 minutes before serving. It will firm up slightly as it cools, making it easier to cut and serve.
Step 9: Serve and Enjoy
Serve warm or at room temperature. For an extra treat, top each serving with a dollop of whipped cream or a scoop of vanilla ice cream. You can also drizzle some caramel sauce for added decadence.

Tips for the Perfect Pumpkin Oatmeal Dump Cake
- Use real pumpkin puree: Avoid pre-sweetened pumpkin pie filling, which already contains sugar and spices.

- Enhance flavor: Sprinkle a little extra cinnamon on top before baking for a stronger spice aroma.
- Make it ahead: This cake tastes even better the next day after the flavors meld together.
- Storage: Store leftovers covered in the refrigerator for up to 4 days. Reheat gently before serving.

Variations to Try
If you want to customize this recipe for different occasions or tastes, here are some easy twists:
1. Pecan Pumpkin Dump Cake
Add ½ cup chopped pecans or walnuts to the oat layer before baking. It brings a nutty crunch that perfectly complements the creamy pumpkin base.
2. Chocolate Pumpkin Dump Cake
Swap the yellow cake mix for a chocolate one and sprinkle chocolate chips on top before baking. The blend of pumpkin spice and chocolate is rich and satisfying.
3. Apple Pumpkin Oat Cake
Add thin slices of apple on top of the pumpkin layer before sprinkling the cake mix. The apple adds natural sweetness and a lovely fruity texture.
4. Gluten-Free Version
Use a gluten-free yellow cake mix and certified gluten-free oats. The flavor remains the same, and everyone can enjoy it.
5. Dairy-Free Option
Substitute melted butter with coconut oil or vegan butter for a dairy-free dessert that’s equally delicious.
How to Store and Reheat
To make the most of this dessert, proper storage is key.
Refrigeration:
After cooling completely, cover the dish tightly with plastic wrap or foil. Refrigerate for up to 4 days.
Freezing:
For longer storage, wrap portions individually and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating:
Warm in a preheated oven at 325°F (165°C) for about 10 minutes, or microwave individual servings for 30–45 seconds until heated through.
FAQs
1. Can I use pumpkin pie filling instead of pumpkin puree?
It’s best to use pure pumpkin puree. Pumpkin pie filling already has added sugar and spices, which would alter the sweetness and flavor balance.
2. Do I have to use yellow cake mix?
No, you can substitute with spice cake mix, white cake mix, or even vanilla cake mix. Each variation slightly changes the flavor profile but keeps the same texture.
3. What type of oats should I use?
Use old-fashioned rolled oats for the best texture. Instant oats can make the topping mushy, while steel-cut oats don’t soften enough during baking.
4. Can I make this recipe in advance?
Yes! This dessert stores beautifully. You can bake it a day ahead, refrigerate, and reheat before serving. In fact, the flavors often deepen overnight.
5. How do I know when it’s fully baked?
The cake is ready when the top looks golden brown, slightly crisp, and the edges are bubbling. The center should appear set but soft.
6. Can I make it without oats?
Yes, simply skip the oats if you prefer a smoother, more traditional dump cake texture. However, oats add a wonderful chewiness and rustic feel.
7. What can I use instead of butter?
You can use melted coconut oil or margarine as substitutes for butter if you’re looking for a dairy-free option.
8. Can I reduce the sugar content?
Absolutely. You can reduce the brown sugar to ⅓ cup without affecting texture much. The pumpkin and cake mix provide enough sweetness.
9. Can I serve this cold?
Yes, while it’s best warm, many enjoy it chilled — similar to pumpkin pie bars. Just top with whipped cream before serving.
10. What’s the difference between a dump cake and a cobbler?
A dump cake uses dry cake mix layered over fruit or filling and “dumped” with butter on top, while a cobbler has a batter or biscuit topping that’s spread over the filling before baking.
