Method
Brown the butter and prep the pan
- Brown the butter in a skillet until golden and nutty, then cool for 10 minutes so it stops cooking.
- Preheat the oven to 350F and grease a 9x13 pan so the blondies release cleanly.
Mix dry ingredients
- Whisk together the all-purpose flour, baking powder, cinnamon, cream of tartar, nutmeg, and salt until evenly combined.
Mix wet ingredients
- Whisk the browned butter and brown sugar until smooth.
- Whisk in the blotted pumpkin puree, then whisk in the eggs and vanilla extract until fully smooth.
Combine and bake
- Fold in the flour mixture, then spread the batter into the greased 9x13 pan.
- Mix the cinnamon sugar topping and sprinkle it generously over the surface.
- Bake for 25-30 minutes at 350F until a toothpick comes out with just a few moist crumbs.
- Cool completely before cutting to keep the chewy snickerdoodle texture from tearing.
Notes
Pro tip: blot the pumpkin puree very dry before mixing—extra moisture can make the center cakier. Store airtight at room temperature up to 3 days or refrigerate up to 5 days; freeze baked bars up to 2 months. For a swap, use a gluten-free 1:1 all-purpose flour blend to make gluten-free blondies while keeping the same baking time range.
