Why You’ll Love this Fall-Inspired Pumpkin Oatmeal Dump Cake
Every single bite of this pumpkin oatmeal dump cake brings the essence of autumn right to your table. I’m talking about warm pumpkin spices, hearty oats, and that irresistible cake mix topping that gets all crispy and golden. What’s not to love?
The best part? It’s ridiculously simple. Just layer, don’t stir, and let your oven do the magic. Perfect for those days when you want something cozy but can’t be bothered with complicated steps.

What Ingredients are in Fall-Inspired Pumpkin Oatmeal Dump Cake?
For this incredibly simple yet decadent autumn dessert, you’ll need just six basic ingredients that combine to create pure magic in your baking dish.
- 1 can (15 oz) pumpkin puree
- 1/2 cup brown sugar
- 1 cup rolled oats
- 1 teaspoon pumpkin spice
- 1 box (15.25 oz) yellow cake mix
- 3/4 cup unsalted butter, melted
While the recipe keeps things wonderfully simple with these core ingredients, you might consider adding chopped pecans or walnuts if you’re craving a bit of textural contrast and nutty flavor to complement the warm spices and creamy pumpkin.
How to Make this Fall-Inspired Pumpkin Oatmeal Dump Cake
Making this pumpkin oatmeal dump cake couldn’t be simpler—it’s the kind of recipe that almost feels like cheating. Start by preheating your oven to 350°F and greasing a 9×13-inch baking pan. The magic of this dessert happens in layers, so resist the urge to stir!
First, spread 1 can (15 oz) of pumpkin puree evenly across the bottom of your prepared pan. Next, sprinkle 1/2 cup brown sugar over the pumpkin, followed by 1 cup of rolled oats and 1 teaspoon of pumpkin spice. These ingredients create the rich, spiced foundation that makes this dessert so quintessentially autumn.
Now comes the best part—the “dump” in dump cake. Take your 15.25 oz box of yellow cake mix and sprinkle it evenly over the previous layers, creating a blanket of dry mix that will transform during baking. Finally, drizzle 3/4 cup of melted unsalted butter all over the cake mix, trying to cover as much of the dry mix as possible. The butter will help the cake mix transform into a golden, slightly crispy topping that perfectly contrasts with the creamy pumpkin layer below.
Pop the pan into your preheated oven and bake for about 40-45 minutes, or until the top turns that irresistible golden brown and the cake feels set when gently touched. For best results, consider using a premium enameled casserole for even heat distribution and that perfect golden crust. Remember, the beauty of dump cakes is in their rustic simplicity, so don’t worry if it doesn’t look picture-perfect—it’s supposed to have that homemade charm.
What to Serve with Fall-Inspired Pumpkin Oatmeal Dump Cake
This heavenly pumpkin oatmeal dump cake pairs up with so many delicious accompaniments that’ll take your dessert game to the next level. I’m talking about a scoop of vanilla ice cream slowly melting into those warm layers, or maybe some freshly whipped cream with a dash of cinnamon on top.
Want something a bit more decadent? Try a drizzle of caramel sauce, which seeps into all those nooks and crannies.
For a morning treat (because who says you can’t have cake for breakfast?), a dollop of Greek yogurt adds a tangy contrast to the sweet pumpkin flavors.
Leftovers and Storage for this Fall-Inspired Pumpkin Oatmeal Dump Cake
Now that you’ve figured out all the yummy ways to serve this dessert, let’s talk about what to do with any cake that’s left (though honestly, that rarely happens in my house!).
This pumpkin cake keeps beautifully in the fridge for up to four days when stored in an airtight container. I recommend covering it with plastic wrap first to prevent it from drying out.
Want to freeze it? Cut into portions, wrap individually, and freeze for up to three months. Reheat in the microwave for 30 seconds, and it’s almost as good as fresh-baked.
Fall-Inspired Pumpkin Oatmeal Dump Cake Substitutions and Variations
Several delicious variations can transform this basic pumpkin oatmeal dump cake into something uniquely yours. Try swapping the yellow cake mix for spice cake or butter pecan for extra warmth. Don’t have pumpkin puree? Sweet potato works beautifully too.
I love adding a cup of chopped pecans or walnuts on top before baking for that irresistible crunch. For a more decadent treat, mix in chocolate chips or dried cranberries with the oats layer.
Can’t do dairy? Coconut oil makes a perfect butter substitute. And why not try a sprinkle of coconut flakes on top? They toast up so nicely in the oven.

Pumpkin oatmeal dump cake often becomes a family tradition once you’ve tried it.
