Method
Prep
- Preheat the oven to 350F and grease a 9x13 pan so the bars release cleanly after baking.
- Whisk the all-purpose flour, baking powder, baking soda, cinnamon, cream of tartar, nutmeg, and salt until evenly combined.
- Whisk the melted unsalted butter and granulated sugar, then add the blotted pumpkin puree, eggs, and vanilla extract.
- Fold the flour mixture into the pumpkin mixture until just combined, then spread the batter evenly into the greased pan.
Cinnamon sugar top and bake
- Mix the cinnamon sugar top (granulated sugar, cinnamon, and cream of tartar) and sprinkle it generously over the entire surface as a thick, even layer.
- Bake at 350F for 25-30 minutes, until the bars are just set and the top looks lightly caramelized; do not overbake for a chewy texture.
Finish
- Cool completely before cutting so the chewy interior sets up and slices stay neat.
Notes
For the best chewy texture, bake only until the center is just set—start checking at 25 minutes. Store covered in the fridge up to 4 days. Freeze baked bars up to 2 months. For a dairy-free swap, use a 1:1 plant-butter replacement (solid-style) in place of the unsalted butter.
