Pumpkin Spice Nutella Cookie Bars with Brown Sugar

These soft, chewy cookie bars combine warm pumpkin spice flavors with rich Nutella in an irresistible layered treat. The bottom layer is a spiced pumpkin cookie base, topped with melted Nutella and finished with more cookie dough for a gooey center. Perfect for fall gatherings or when you want something more special than regular cookies but easier than a layered cake. The brown sugar adds deep molasses notes that complement both the pumpkin and chocolate beautifully.

FAQ

Can I use regular chocolate chips instead of Nutella?

Chocolate chips won't create the same gooey layer. Melt chips with a tablespoon of butter for better spreading consistency.

How long do these keep at room temperature?

Store in an airtight container for up to 3 days. The texture stays soft and chewy for the first two days.

Can I freeze these cookie bars?

Yes, wrap individually or store in freezer bags for up to 1 month. Thaw at room temperature before serving.
