Method
Prep the pan and oven
- Preheat the oven to 350 F (175 C) and line a 9x9-inch pan with parchment paper, leaving overhang for easy lifting.
Make the blondie batter
- Whisk the melted butter with both sugars until smooth and glossy, with no dry sugar pockets.
- Whisk in the pumpkin puree, egg yolk, and vanilla extract until the mixture looks evenly orange and thick.
- Stir in the all-purpose flour, baking soda, salt, and pumpkin pie spice just until combined, stopping as soon as no streaks of flour remain.
Add chips and pecans
- Fold in 3/4 cup of the white chocolate chips and the chopped pecans so they are evenly distributed through the batter.
- Spread the batter in the pan and sprinkle the remaining white chocolate chips over the top for a crackly finish.
Bake and cool
- Bake at 350 F (175 C) for 25 to 30 minutes, until the edges are golden and a toothpick comes out with moist crumbs.
- Cool completely in the pan so the blondies set and lift cleanly before cutting.
Notes
For the fudgy-chewy texture, don’t overbake—pull the pan when the center still looks slightly underdone with moist crumbs on a toothpick. Store in an airtight container at room temperature for up to 3 days or refrigerate for up to 5 days; freeze baked blondies (well wrapped) for up to 2 months. Swap option: use dairy-free white chocolate chips and plant-based butter to make them dairy-free without changing bake time.
