This dessert was created to capture the warm comfort of pumpkin pie in a form that is easier to share and enjoy. With a spiced pumpkin filling layered between a buttery crust and a crisp oat topping, it is a treat that fits perfectly into any autumn gathering or cozy family evening.

I first tried layering pumpkin with oats during a holiday season when I wanted something different from pie, and it quickly became a family favorite.

Ingredients

  • Cooking spray: for greasing the pan evenly and preventing sticking
  • Cold unsalted butter: ensures a flaky crust and crumbly topping
  • Granulated and light brown sugar: provide sweetness and depth with a hint of molasses
  • Pure vanilla extract: enhances the aroma and rounds out flavors
  • Old fashioned oats: create texture and a rustic crunch
  • All purpose flour: forms the structure of the crust and topping
  • Ground cinnamon and pumpkin pie spice: bring warmth and classic autumn spice
  • Kosher salt: balances sweetness and sharpens flavors
  • Eggs: bind the filling and give it richness
  • Honey: adds natural sweetness and floral depth
  • Pumpkin puree: delivers the smooth earthy base of the dessert
  • Heavy cream: adds a silky texture and richness to the filling
  • Nutmeg: offers warmth and complements pumpkin beautifully

Step-by-Step Instructions

Prepare the Base:
Grease a rectangular baking pan with cooking spray and line with parchment. Cream butter, granulated sugar, brown sugar, and vanilla in a stand mixer until light and smooth, about four minutes. Add lightly crushed oats, flour, cinnamon, and salt. Mix until combined, then press into the prepared pan. Chill for at least twenty minutes, then bake at 350 degrees until just firm, about ten minutes.
Make the Filling:
Whisk eggs, honey, sugars, and vanilla until smooth. Stir in pumpkin puree, cream, pumpkin pie spice, nutmeg, and salt. Mix until fully incorporated.
Prepare the Topping:
Beat brown sugar and cold butter in a stand mixer until blended. Add oats, flour, and salt, lightly breaking down oats with your fingers. Mix until crumbly.
Assemble and Bake:
Spread pumpkin filling evenly over baked base. Cover with foil, slit open for steam, and bake until just set, about fifty minutes. Remove foil, sprinkle topping evenly, and bake again until golden and crisp, about fifteen minutes more.
Cool and Serve:
Let bars cool for at least half an hour or refrigerate overnight for clean cuts and the best flavor.

Pumpkin is one of my favorite ingredients to bake with. I remember making these bars for the first time with my kids and how excited they were to crumble the oat topping over the filling. That extra crunch has become the most requested part of the dessert.

Storage Tips

These bars store beautifully in the fridge for up to a week. Keep them covered in an airtight container to prevent them from drying out. For longer storage, wrap tightly and freeze for up to two months.

Ingredient Substitutions

Maple syrup can replace honey for a deeper sweetness. For a dairy free version, swap butter with coconut oil and cream with coconut cream. Rolled oats are best, but quick oats work in a pinch.

Serving Suggestions

Serve chilled for clean cuts and best texture. Pair with coffee or spiced tea. A dollop of whipped cream or drizzle of caramel makes them extra special for a holiday table.

Cultural Notes

Pumpkin pie has deep roots in North American traditions, especially around harvest festivals and Thanksgiving. Transforming those familiar flavors into a bar makes them more approachable for casual gatherings and adds a playful twist to a classic.

Steps to Follow

Step 01

Grease a 13x9 inch pan with cooking spray and line with parchment paper. In a stand mixer fitted with paddle attachment, beat butter, granulated sugar, brown sugar, and vanilla on high speed until smooth and creamy, about 4 minutes.

Step 02

Gently crush oats to break into smaller pieces. Slowly add oats, flour, cinnamon, and salt, beating on medium-low speed until blended, 1-2 minutes.

Step 03

Press base mixture into bottom of prepared pan. Cover and refrigerate at least 20 minutes or up to 1 day.

Step 04

Preheat oven to 350°F. Bake base until beginning to firm up, about 10 minutes.

Step 05

In a large bowl, whisk eggs, honey, granulated sugar, brown sugar, and vanilla until well combined.

Step 06

Add pumpkin puree, cream, pumpkin pie spice, nutmeg, and salt. Stir with wooden spoon until combined.

Step 07

Clean stand mixer bowl and paddle. Beat brown sugar and butter on medium speed until combined. Break down oats with fingers while adding for varied texture. Add flour and salt, beating on low speed until just combined.

Step 08

Pour pumpkin filling over base in pan. Cover with foil and cut a large slit lengthwise down center. Bake until filling starts to set, about 50 minutes.

Step 09

Remove foil and crumble oat topping over surface, leaving some filling exposed. Continue baking until topping crisps up, about 15 minutes more.

Step 10

Let cool at least 30 minutes, or ideally refrigerate up to 1 day before cutting into bars.

Extra Tips

  1. For firmer base, pre-bake before adding filling. For softer base, skip pre-baking step.
  2. Add oat topping only after filling sets to maintain distinct crunchy layer.
  3. Bars taste better the next day after chilling in refrigerator.
  4. Can be stored in refrigerator for up to one week.
