Warm and chewy, Pumpkin Blondies bake into soft squares made with brown butter, pumpkin, and spice. White chocolate melts in gently, adding a creamy contrast to the pumpkin-rich batter.
Preheat the oven to 350 degrees Fahrenheit (175 degrees Celsius). Line a 9×13-inch baking pan with foil or parchment paper, leaving an overhang.
Cook the butter in a heavy saucepan over medium heat, stirring constantly until it foams, turns clear, and then turns a deep brown, about 5 or 6 minutes. Pour the browned butter into a glass measuring cup with a handle to cool slightly.
In a large bowl, combine the flour, cinnamon, ginger, nutmeg, allspice, and salt.
In another medium bowl, whisk together the cooled browned butter, brown sugar, egg, vanilla, and pumpkin.
Add the butter mixture to the flour mixture, stirring until just combined. Fold in the white chocolate chunks. Pour the batter into the prepared baking pan.
Bake for 35 minutes, or until a cake tester or toothpick inserted into the center comes out clean with a few moist crumbs. Set the pan on a wire rack to cool completely before cutting into squares.
Notes
To store, keep Pumpkin Blondies in an airtight container at room temperature for up to 3 days. If your kitchen tends to be warm, refrigerate them in a sealed container and they’ll stay good for up to 1 week.To freeze, let them cool completely, then wrap each square in plastic wrap and place them in a freezer-safe bag or container. They’ll keep well for 2 to 3 months. To reheat, thaw at room temperature or microwave a square for about 10 to 15 seconds if you want it soft and warm again.
