Prep and mix
- Preheat oven to 350F and grease a 9x13 pan. Set up the pan so the batter can go in right after mixing.
- Whisk together all-purpose flour, pumpkin pie spice, cinnamon, baking soda, baking powder, and salt. Whisk until the dry mixture is evenly speckled.
- Whisk pumpkin puree, granulated sugar, brown sugar, packed, vegetable oil, eggs, and vanilla extract until smooth. Keep whisking until no sugar streaks remain.
- Fold dry ingredients into wet ingredients until just combined, then fold in 1-1/2 cups semi-sweet chocolate chips. Stop mixing as soon as no dry flour pockets are visible.
Bake and finish
- Spread the batter evenly into the greased 9x13 pan. Smooth the top so it bakes uniformly.
- Scatter the remaining semi-sweet chocolate chips over the top. Aim for even coverage so you get chocolate pockets throughout.
- Bake at 350F for 25-30 minutes, until a toothpick comes out clean. Look for a set, slightly domed top with edges pulling away from the pan.
- Cool completely before cutting into bars. Wait until fully cool to slice clean bars with a tender crumb.
Notes
Pro tip: fold the dry ingredients in gently to keep the bars tender and prevent a tough crumb. Store in an airtight container at room temperature up to 3 days or refrigerate up to 5 days. Freeze bars (well wrapped) for up to 2 months. For a dietary swap, use a plant-based egg replacer in a 1:1 substitution to make them egg-free.
