Method
Prep and preheat
- Preheat oven to 350F and grease a 9x13 pan.
Mix dry ingredients
- Whisk all-purpose flour, pumpkin pie spice, cinnamon, baking soda, baking powder, and salt in a bowl until evenly combined.
Mix wet ingredients
- Whisk pumpkin puree, granulated sugar, brown sugar, vegetable oil, eggs, and vanilla extract until smooth and glossy.
Combine and add chips
- Fold the dry ingredients into the wet ingredients until just combined, then fold in 1-1/2 cups semi-sweet chocolate chips.
Bake
- Spread the batter evenly in the greased pan and scatter the remaining chocolate chips over the top.
Check doneness
- Bake for 25-30 minutes at 350F until a toothpick comes out clean.
Cool and cut
- Cool completely before cutting into bars so the crumb sets and slices hold together.
Notes
For the cleanest slices, let the bars cool fully at room temperature (about 1-2 hours) before cutting; any warmth makes them crumble. Store airtight in the refrigerator up to 5 days; freeze bars up to 2 months for grab-and-go. For a lighter option, you can replace vegetable oil with an equal amount of unsweetened applesauce, though the texture will be slightly softer.
