Method
Prep and mix
- Preheat the oven to 350F and grease a 9x13 baking pan so the brownies release easily after baking.
- Combine the brownie mix, pumpkin puree, pumpkin pie spice, and cinnamon in a bowl and stir until completely smooth.
- Fold in the dark chocolate chips if using, distributing them evenly through the thick batter.
Bake, cool, and finish
- Spread the dense batter evenly into the prepared pan using a spatula for full coverage.
- Bake for 23-26 minutes at 350F until a toothpick comes out clean.
- Cool completely, then dust with powdered sugar and cut into 16 bars.
Notes
Pro tip: because the batter will be very thick, expect it to spread slowly—take a few extra minutes to level it for even baking. Store airtight in the fridge for up to 4 days; freeze baked bars up to 2 months. For a dairy-free option, choose a brownie mix labeled dairy-free (the recipe itself uses no eggs or oil).
