Brown butter and prep
- Brown the butter until golden and nutty, then cool for 10 minutes so it won’t scramble the eggs.
- Preheat the oven to 350°F and grease a 9x13 pan so the blondies release cleanly.
Mix batter
- Whisk together the all-purpose flour, baking powder, cinnamon, cream of tartar, nutmeg, and salt to evenly distribute the leavening and spices.
- Whisk the browned butter and brown sugar until smooth, then add the blotted pumpkin, eggs, and vanilla extract and whisk until fully combined.
- Fold in the flour mixture just until no dry streaks remain, then spread the batter evenly in the pan.
Top and bake
- Mix the cinnamon sugar (granulated sugar plus cinnamon) and sprinkle generously over the top for a snickerdoodle-style crust.
- Bake for 25–30 minutes at 350°F until a toothpick comes out with just a few moist crumbs, then keep the pan in place to avoid overbaking.
- Cool completely before cutting so the chewy centers set and the cinnamon sugar crust stays intact.
Notes
Pro tip: blotting the pumpkin very dry helps prevent gummy centers, and cooling the blondies completely ensures clean squares. Store covered at room temperature up to 3 days or refrigerate up to 5 days. Freezing is yes—freeze individual bars in a sealed container up to 2 months. For a dairy-free swap, use a 1:1 plant-butter substitute; brown it the same way for the best flavor.
