Pumpkin Crumble is a delicious dessert mash-up of pumpkin pie and crumb cake. Super easy and budget-friendly, this recipe uses a box of yellow cake mix and canned pumpkin for tasty shortcuts. This is the easy pumpkin dessert recipe you've been searching for to feed a crowd at Thanksgiving!

I'm seriously considering replacing the pumpkin pie at Thanksgiving with this super scrumptious dessert.
That might be unheard in some parts, but I'm pretty sure I could get away with it here. Pumpkin Spice Crumble, along with Pumpkin Trifle and Two Layer Pumpkin Cheesecake, is always a crowd pleaser. It's rich and packed full of pumpkin pie flavor, yet easier to make, serve and eat than a pie.

That's because this delicious dessert is a box cake hack or "dump cake". Rather than making a traditional crust, we use a yellow cake mix, butter and an egg to create a rich bottom layer.
But the best part?--That buttery, spiced crumble topping, that gets even better with Easy Homemade Whipped Cream!

🥘Just Simple Pantry Ingredients Needed

- yellow cake mix- 1 cup of this is reserved for the topping; Duncan Hines is my preferred brand because you get more in the box
- butter- for richness
- eggs- use at room temperature for easier mixing
- canned pumpkin- for convenience, but you can use fresh
- cinnamon, nutmeg & ginger- warm spices to accent the pumpkin's flavor
- brown sugar- sweetness with a hint of molasses to elevate the flavor profile
- evaporated milk- for creaminess and richness
- reserved cake mix, sugar, cinnamon, & butter- for the tasty crumble topping
🔪How To Make Pumpkin Crumble

- Step 1: Make the base by mixing the cake mix with butter and egg; reserve some cake mix for crumb topping. Spread mixture into pan.

- Step 2: Combine the pumpkin, brown sugar, spices, and milk; spread on top of cake layer.

- Step 3: Mix the reserved cake mix, sugar, cinnamon, and butter; sprinkle on top of pumpkin layer.

- Step 4: Bake uncovered for 40-45 minutes; serve warm or chilled.
Hint: The bottom cake layer will be thick. Use a sturdy scraping spatula to spread it evenly in the pan.
🥣Easy Substitutions
- Pumpkin: feel free to use your own pumpkin or sweet potatoes instead
- Cake Mix: use spice cake mix for more warm spice flavor
- Milk: heavy cream or half and half can be used instead of the evaporated milk
📖Pumpkin Crumble Recipe Variations
- Pecan Crunch Pumpkin Crumble: For an extra layer of irresistible texture, toss a half cup of chopped pecans or walnuts right into your buttery cake mix topping before baking. It pairs perfectly with those warm fall spices!
- Chocolate Chip Pumpkin Pie Crumble: If your family loves chocolate, try sprinkling a cup of semi-sweet chocolate chips directly over the pie layer before adding your crumb topping. Pumpkin and chocolate are a surprisingly fantastic combination!
- Caramel Swirl Pumpkin Crumble: For a truly decadent twist on this easy dessert, drizzle a rich, gooey caramel sauce over the top of your baked pumpkin pie crumble just before serving. It adds a wonderful depth of flavor that your Thanksgiving guests will go crazy for!

🍶Storing Pumpkin Crumble
Cover Pumpkin Pie Crumble with foil or store in an airtight container. Refrigerate for up to 3 days.
To reheat, cover with aluminum foil and place in a 325 degree oven for 10-15 minutes or until heated through.
✅Betty's Top Tip: Choose the Right Cake Mix
When making this pumpkin crumble, I highly recommend reaching for a box of Duncan Hines yellow cake mix! It is one of the few brands that still gives you a few extra ounces in the box. That little bit of extra volume is super important since we need to reserve a full cup of the dry mix to create that perfect, buttery topping.
❓Pumpkin Pie Crumble FAQ
You can use a 30 oz. can of pumpkin pie mix for this recipe (Libby's makes it). If you choose this option, it will replace the canned pumpkin, brown sugar and spices in the pie layer.
Yes! Because the filling is essentially a rich, custardy pumpkin pie, it needs to be chilled. Once your dessert has completely cooled, cover the pan tightly with aluminum foil or transfer the squares to an airtight container. It will stay perfectly fresh in the fridge for up to 3 days.
Absolutely! While I prefer a classic yellow cake mix for that traditional buttery flavor, a spice cake mix is a fantastic substitution if you want to amplify those warm, cozy fall spices. Just remember to reserve that one cup of the dry mix for your crumble topping!
You will know it is ready to pull from the oven when the buttery crumb topping is a beautiful golden brown. If you give the baking pan a gentle shake, the center of the pumpkin layer should be completely set and shouldn't jiggle. Let it stand for at least 5 minutes before serving so it can firm up perfectly for clean slices!
