Ingredients Equipment Method Notes

Ingredients
  

brownie mix
  • 1 box (18 oz) dark chocolate or fudge brownie mix Use a mix that typically calls for eggs and oil—leave those out and replace with pumpkin.
pumpkin puree
  • 1 can (15 oz) pumpkin puree No eggs and no oil are needed because the pumpkin replaces them.
spices
  • 0.5 tsp pumpkin pie spice
  • 0.5 tsp cinnamon
optional mix-in
  • 0.25 cup dark chocolate chips Optional—stir into the thick batter.
topping
  • powdered sugar For dusting the cooled brownies.

Equipment

  • 1 sheet pan

Method
 

Prep and preheat
  1. Preheat the oven to 350°F, then grease a 9x13 baking pan so the brownies lift out easily.
Mix the batter
  1. Combine the brownie mix, pumpkin puree, pumpkin pie spice, and cinnamon in a mixing bowl and stir until completely smooth.
  2. Stir until the batter looks very thick—this is correct, and you should not add eggs or oil from the box instructions.
  3. Fold in the dark chocolate chips if using so they distribute throughout the thick batter.
Bake
  1. Spread the batter evenly in the prepared pan; because it is dense, press and level it with a spatula.
  2. Bake at 350°F for 23–26 minutes, until a toothpick comes out clean.
Cool and finish
  1. Cool completely, then dust the top with powdered sugar.
  2. Cut into 16 bars and serve; each bar is approximately 90–100 calories depending on the brownie mix used.

Notes

Pro tip: don’t loosen the batter—its thick consistency is what helps these bake up dense and fudgy without eggs or oil. Store bars in an airtight container in the fridge for up to 4 days; freeze for up to 2 months (thaw overnight in the refrigerator) if you want to make ahead. For a dairy-free option, choose a brownie mix and chips that are labeled dairy-free.
