Method
Prep the pan and oven
- Preheat oven to 350F, then grease a 9x13 pan (even coverage helps prevent sticking).
Mix dry and wet batters
- Whisk all-purpose flour, pumpkin pie spice, cinnamon, baking soda, baking powder, and salt until evenly combined (no visible spice pockets).
- Whisk pumpkin puree, granulated sugar, brown sugar, vegetable oil, eggs, and vanilla extract until smooth and glossy (no streaks of sugar).
Combine and bake
- Fold the dry mixture into the wet until just combined, then fold in 1-1/2 cups chocolate chips (stop when no dry flour remains).
- Spread the batter evenly in the pan, then scatter the remaining chocolate chips over the top for dark pockets.
- Bake at 350F for 25-30 minutes until a toothpick comes out clean (golden-orange edges with set centers).
Cool and cut
- Cool completely before cutting into bars so the crumb sets and the chocolate stays intact.
Notes
For clean slices, let the pan cool fully on a rack before cutting, and if your kitchen is warm, chill the pan 1-2 hours for extra neat edges. Store airtight at room temperature up to 3 days or refrigerate up to 7 days. Freeze bars up to 2 months, wrapped well, then thaw overnight in the fridge. For a lower-sugar option, use a 1:1 baking brown sugar substitute and reduce granulated sugar slightly (taste the batter before baking).
