Brown butter & prep
- Brown the butter in a cast iron skillet over medium heat until golden and nutty, then cool for 10 minutes so it doesn’t scramble the eggs.
- Preheat the oven to 350°F and grease a 9x13 pan to prevent sticking.
Mix batter
- Whisk together all-purpose flour, baking powder, cinnamon, cream of tartar, nutmeg, and salt until evenly combined.
- Whisk the browned butter and brown sugar until smooth, then mix in the blotted pumpkin puree, eggs, and vanilla extract until fully combined.
- Fold the flour mixture into the wet ingredients and spread the thick batter evenly in the prepared pan.
Cinnamon sugar top & bake
- Mix the cinnamon sugar with granulated sugar and cinnamon, then sprinkle generously over the top so it forms a fragrant crust.
- Bake at 350°F for 25–30 minutes until a toothpick comes out with just a few moist crumbs.
- Cool the blondies completely before cutting to keep the snickerdoodle texture chewy and the slices clean.
Notes
For the best chewy texture, blot the pumpkin puree very dry before mixing—extra moisture can make the blondies cakier. Store airtight at room temperature up to 3 days or refrigerate up to 5 days; freeze bars up to 2 months. For a dairy-light swap, use browned plant-based butter in the same quantity, and watch the browning closely since some brands toast faster.
