Why You’ll Love These Pumpkin Streusel Bars

These bars offer the richness of pumpkin pie with the satisfying texture of a streusel topping.

Can I Use Fresh Pumpkin Instead of Canned?

Yes, you can! If using fresh pumpkin puree, make sure it’s well-drained and smooth. Canned pumpkin is consistent and easy to use, which makes it perfect for fuss-free baking. Just avoid pumpkin pie filling, which already includes sugar and spices.

How To Make the Pumpkin Streusel Bars

Step 1: Prepare the Crust

Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper. In a bowl, combine 1 cup flour, 1/4 cup granulated sugar, 1/4 teaspoon salt, and 1/2 cup melted unsalted butter. Mix until crumbly. Press evenly into the prepared pan and bake for 12 minutes. Let cool slightly.

Step 2: Make the Pumpkin Filling

In a mixing bowl, whisk together 1 cup pumpkin puree, 1/2 cup brown sugar, 1/2 teaspoon pumpkin pie spice, 1/2 teaspoon cinnamon, 1/4 teaspoon salt, 1 large egg, and 1 teaspoon vanilla extract until smooth. Pour the mixture over the slightly cooled crust.

Step 3: Prepare the Streusel Topping

In another bowl, stir together 1/2 cup old-fashioned oats, 1/3 cup flour, 1/4 cup brown sugar, 1/4 teaspoon cinnamon, and 3 tablespoons melted unsalted butter. Sprinkle evenly over the pumpkin filling.

Step 4: Bake and Cool

Bake for 30–35 minutes or until the center is set and the edges are lightly golden. Cool completely in the pan before lifting out with the parchment and slicing into 16 bars.

Best Way to Store Your Pumpkin Bars
