Pumpkin pie crumble bars have all the warm, delicious flavors of pumpkin pie, in an easy-to-serve bar.
This easy-to-make Thanksgiving dessert is loaded with rolled oats, brown sugar, canned pumpkin, and spices!

Pumpkin Pie is a traditional holiday dessert, but sometimes you just want to change things up a bit.
This is where pumpkin pie crumble bars come in. It's kind of like having a granola bar and a piece of pumpkin pie in one bite.
After tasting one of these babies, I think you'll agree that oatmeal and pumpkin were made for each other.
Your family will love eating these bars to top off an amazing Thanksgiving dinner, and you'll love how easy they are to make!
What you need
- pumpkin puree
- sweetened condensed milk
- egg
- butter
- rolled oats (quick cook works best)
- oat flour (see tips for success for making homemade oat flour)
- light brown sugar
- baking soda, baking powder and salt
- pumpkin pie spice
Step-by-step instructions
Step 1: Make the crumble crust
Preheat the oven to 350°F (176°C). Line a 9" x 13" baking pan with parchment paper.
Mix the crust ingredients together in a large mixing bowl. Set aside 1 heaping cup for the crumble topping.
Press the remaining mixture into the bottom of the pan. Bake for 10 minutes and remove from oven. (Leave the oven on!)

Step 2: Make the filling
Using an electric mixer or a spatula, beat the pumpkin puree, sweetened condensed milk, egg, and pumpkin pie spice together until smooth.
Pour the filling over the crust and smooth evenly with a spatula.

Step 3: Add the crumble topping
Sprinkle the remaining crumble mixture evenly over the top of the filling.

Step 4: Bake
Bake for 40 minutes.

Step 5: Cool
Let cool completely on the countertop before chilling in the fridge for 1- 2 hours.
This will help them to set up and make it easier to slice into squares.
Cut into 24 squares and serve!

Tips for Success
- You can make your own oat flour if you have a high-speed blender or a food processor. Place 2 cups of rolled oats into the blender/processor and pulse until the oats have a fine, flour-like consistency.
- Use Gluten-Free Oats to make this a gluten-free dessert.
- Use parchment paper to prevent the bars from sticking to the pan. If you don't have parchment paper, make sure you generously grease the bottom and sides of the baking pan.
- You can make these the day before you want to serve them to free up valuable oven space during the holidays!
- These bars taste amazing with homemade whipped cream on top!
- Add chopped nuts like pecans or walnuts to the top before the final bake for added texture and flavor.
- Store these bars in an air-tight container in the fridge for up to 3 days.

I’m trying these for the first time (they are in the oven). I was wondering if they can be frozen for a couple of weeks? Birthday today, leftovers for Thanksgiving!
Amy says
Yes, they can be frozen for up to 3 months.

These are incredible!!! I love pumpkin pie and anything made with oats.
Since I have a vegan member in my family, I am going to play around with it to see if I can make it vegan or at least vegetarian. Maybe I will use vegan butter and/or coconut oil, replace some of the sugar with maple syrup and possibly cashew milk for the sweetened condensed milk. I did sprinkle some mini chocolate chips on the one I made right after I took it out of the oven. More decadent but definitely delicious! Every recipe I have ever made of yours has been wonderfully! Thanks!

Can I use regular flour instead of oat?
Amy says
I've never used regular flour in this recipe so I can't recommend it with confidence.
