Method
Brown the butter
- Melt the unsalted butter over medium heat until it turns golden and smells nutty, about 5–8 minutes, then remove from heat.
- Cool the browned butter for 10 minutes so it’s warm, not hot.
Prep and preheat
- Preheat the oven to 350°F and grease a 9x13 pan.
Mix the dry ingredients
- Whisk all-purpose flour, baking powder, cinnamon, cream of tartar, nutmeg, and salt until evenly combined.
Mix the blondie batter
- Whisk browned butter and brown sugar until smooth.
- Whisk in blotted pumpkin puree, eggs, and vanilla extract until the batter is smooth.
Assemble and bake
- Fold the flour mixture into the wet mixture until no dry streaks remain, then spread the batter in the pan.
- Mix granulated sugar and cinnamon, then sprinkle generously over the top.
- Bake for 25–30 minutes at 350°F until a toothpick comes out with just a few moist crumbs.
- Cool completely before cutting so the bars set cleanly.
Notes
Pro tip: blotted very dry pumpkin puree prevents cakey blondies and helps keep the chewy snickerdoodle texture. Store airtight at room temperature up to 3 days or refrigerate up to 5 days; freeze bars up to 2 months. For a lower-sugar option, reduce brown sugar by 1/4 cup and use a 1:1 brown sugar substitute if desired.
