Method
Prep the oven and pan
- Preheat the oven to 350F, then grease a 9x13 pan.
- Whisk all-purpose flour, pumpkin pie spice, cinnamon, baking soda, baking powder, and salt in a bowl.
Mix the batter
- Whisk pumpkin puree, granulated sugar, brown sugar, vegetable oil, eggs, and vanilla extract until smooth.
- Fold the dry mixture into the wet mixture just until combined, then fold in 1-1/2 cups chocolate chips.
Bake and cool
- Spread the batter evenly in the pan, then scatter the remaining chocolate chips over the top.
- Bake for 25-30 minutes at 350F, until a toothpick comes out clean.
- Cool completely before cutting into bars, so the crumb sets and slices stay tidy.
Notes
For the cleanest bar slices, let the pan cool fully before cutting—chocolate chips firm up and the crumb loses moisture. Store covered at room temperature up to 3 days or refrigerate up to 5 days. Freezing is yes: freeze airtight up to 2 months, thaw overnight in the fridge. For a lighter option, swap half the vegetable oil for unsweetened applesauce (bars may be slightly softer).
