Method
Brown the butter
- Brown the butter until golden and nutty, then cool for 10 minutes.
- Preheat the oven to 350F and grease a 9x13 pan.
Mix the batter
- Whisk the 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 add the blotted pumpkin puree, eggs, and vanilla extract and whisk until smooth.
- Fold in the flour mixture, then spread the batter evenly in the prepared pan.
Top and bake
- Mix the cinnamon sugar (granulated sugar plus cinnamon) and sprinkle generously over the top.
- Bake for 25-30 minutes, until a toothpick comes out with just a few moist crumbs.
- Cool completely before cutting into squares so the chewy texture sets.
Notes
Pro tip: blot the pumpkin puree very dry so the bars bake up thick and chewy instead of cakey. Store airtight at room temperature for up to 3 days or refrigerate for up to 5 days; freeze baked squares for up to 2 months. For a dairy-free swap, use a 1:1 plant butter for browning (note the flavor will be slightly different).
