Method
Prep the oven and pan
- Preheat the oven to 350F, then grease a 9x13 pan.
- Use a 9x13 pan so the batter bakes evenly across a thin bar layer.
Mix dry and wet
- Whisk all-purpose flour, baking powder, baking soda, cinnamon, cream of tartar, nutmeg, and salt until evenly combined.
- Whisk melted butter and granulated sugar together, then add the blotted pumpkin, eggs, and vanilla extract and mix until smooth.
Combine, top, and bake
- Fold the flour mixture into the pumpkin batter until just combined, then spread the batter in the greased pan.
- Mix the cinnamon sugar topping ingredients, then sprinkle generously over the entire surface.
- Bake for 25-30 minutes at 350F until just set; do not overbake so the bars stay chewy.
Cool and cut
- Cool the bars completely before cutting so they set cleanly and keep their soft, chewy texture.
Notes
Pro tip: blot the pumpkin puree dry before mixing—this helps the bars bake into a soft, chewy interior instead of turning cakey. Store airtight at room temperature up to 3 days or refrigerate up to 5 days; freeze up to 2 months. For a lighter option, use a 1:1 baking-style substitute for part or all of the butter, keeping the bake time the same for a chewy set.
