Pumpkin Pie Crisp with Buttery Oat Crumble
This pumpkin pie crisp gives you all the spiced custard flavor of a classic pumpkin pie, topped with a golden, buttery oat crumble instead of a traditional crust.

It’s easier than rolling out pie dough, bakes in one dish, and fills your kitchen with that cozy pumpkin spice scent.
Why This Pumpkin Crisp Disappears First
The filling leans on sweetened condensed milk, which keeps the custard silky without needing extra sugar or cream. It sets up into a smooth, sliceable layer that tastes like the richest part of a pumpkin pie.
Up top, a nubby oat and pecan crumble bakes into crunchy, caramelized clusters. Every spoonful has that contrast of velvety custard and crisp, buttery topping. It’s the dessert everyone asks for a second scoop of.
Ingredients

- 15 oz can pumpkin puree: not pumpkin pie filling, which has added sugar and spice
- 14 oz can sweetened condensed milk: regular, not fat-free, for the creamiest texture
- 2 large eggs: at room temperature so they blend in smoothly
- 1 tsp vanilla extract: pure vanilla gives the best depth
- 1 ½ tsp pumpkin pie spice: a blend of cinnamon, ginger, nutmeg, and clove
- ¼ tsp salt: balances the sweetness
- 1 cup old-fashioned rolled oats: not instant, so the topping stays crisp
- ½ cup all-purpose flour: helps bind the crumble
- ½ cup packed brown sugar: light or dark both work
- ½ cup chopped pecans: optional, but they add a toasty crunch
- ½ tsp ground cinnamon: extra warmth in the topping
- 6 tbsp cold unsalted butter: cut into small cubes
Variations / Substitutions
- Nuts: swap pecans for walnuts or sliced almonds, or leave them out for a nut-free crisp.
- Gluten-free: use certified gluten-free rolled oats and a 1:1 gluten-free flour blend.
- Dairy-free: replace the butter with a plant-based stick and swap the condensed milk for a can of full-fat coconut milk plus ¾ cup sugar, though the filling will be a little softer.
- Spice: add a pinch of ground ginger or cardamom for extra warmth.
If you love the classic, a traditional pumpkin pie is always a hit.
How to Make Pumpkin Pie Crisp
Step 1: Whisk the Pumpkin Filling

In a large bowl, whisk together the 15 oz pumpkin puree, 14 oz sweetened condensed milk, 2 eggs, 1 tsp vanilla, 1 ½ tsp pumpkin pie spice, and ¼ tsp salt until completely smooth.
The mixture should look glossy and feel thick but pourable. If it appears lumpy, keep whisking; those lumps are just undissolved spice or egg.
Step 2: Mix the Oat Crumble

In a separate bowl, stir together the 1 cup oats, ½ cup flour, ½ cup brown sugar, ½ cup pecans (if using), and ½ tsp cinnamon. Add the 6 tbsp cold butter cubes and work them in with your fingertips or a pastry cutter until the mixture looks like coarse crumbs with pea-sized butter pieces.
You’re after a mix of fine, sandy bits and larger clumps. Those bigger pockets of butter will melt during baking and create crisp, golden shards in the topping.
Step 3: Assemble the Crisp

Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish with butter or nonstick spray. Pour the pumpkin filling into the dish and spread it evenly with a spatula.
Scatter the oat crumble across the top, covering every bit of custard. Don’t press it down; let it mound lightly so it bakes into a craggy, crunchy lid.
Step 4: Bake the Crisp

Bake for 45 to 50 minutes, until the filling is set at the edges but still has a slight jiggle in the center, and the topping is deep golden brown.
Your kitchen will smell like toasted spices and brown sugar when it’s close. If the crumble darkens too fast, loosely tent the dish with foil for the last 10 minutes.
Step 5: Cool and Serve

Let the crisp cool on a wire rack for at least 30 minutes. This rest firms up the custard so it slices or scoops cleanly.
Dish it into bowls and add a cloud of whipped cream or a scoop of vanilla ice cream. The filling will be velvety and warmly spiced, the crumble buttery and crisp. Serve it warm.
A Few Tips for Foolproof Pumpkin Crisp
- Bring your eggs to room temperature: so they blend evenly into the pumpkin mixture without streaking. Pull them from the fridge 30 minutes ahead.
- Stop mixing the crumble as soon as those pea-sized butter bits appear. Overworking melts the butter and turns the topping into a paste.
- Chill overnight for neat squares. As the crisp cools completely, the custard sets almost like a pumpkin pie bar.
- Toast the pecans first: if you want a deeper nutty flavor. Bake them on a sheet pan at 350°F for 5 to 7 minutes, then let them cool before adding.
Bake times by pan:
| Pan size | Bake time |
|---|---|
| 8×8-inch square | 50–55 minutes |
| 9×13-inch rectangle | 45–50 minutes |
| 9-inch pie dish | 55–60 minutes |
Storing and Reheating Leftovers
- Refrigerate: Cover the cooled crisp and keep it in the fridge for up to 4 days.
- Reheating: Warm single portions in the microwave for 30 to 45 seconds, or place the whole dish (covered) in a 300°F oven for 15 minutes to re-crisp the topping.
- Serve Cold: Straight from the fridge, the filling turns dense and almost cheesecake-like. It’s a great cold dessert too.
Frequently Asked Questions
Can I freeze this pumpkin pie crisp?
Yes. Let it cool completely, wrap it tightly, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating or serving cold.
What’s the difference between pumpkin puree and pumpkin pie filling?
Pumpkin puree is just cooked, mashed pumpkin with no added sugar or spices. Pumpkin pie filling comes pre-sweetened and spiced. This recipe relies on puree so you control the sweetness and flavor.
Can I use quick oats instead of old-fashioned oats?
You can, but the topping will be softer and less crunchy. Old-fashioned oats hold their shape and give the crumble its signature crispness.
My filling turned out too soft even after cooling. What went wrong?
It likely needed more oven time. The center should wobble gently but not slosh when you nudge the pan. If the topping browns before the custard sets, tent with foil and bake a few extra minutes.
