Ingredients
  

90 Calorie Pumpkin Brownies
  • 1 box (18 oz) dark chocolate or fudge brownie mix Use a mix that yields 16 brownies if possible; calories will vary slightly by brand.
  • 1 can (15 oz) pumpkin puree Replace eggs and oil from the box entirely with pumpkin puree.
  • 0.5 tsp pumpkin pie spice
  • 0.5 tsp cinnamon
  • 0.25 cup dark chocolate chips Optional; fold in to boost chocolate pockets.
  • powdered sugar For dusting after cooling.

Equipment

  • 1 sheet pan

Method
 

Prep the pan and heat oven
  1. Preheat the oven to 350F and grease a 9x13 baking pan.
  2. The oven should fully preheat before baking so the brownies set evenly.
Mix the batter
  1. Combine the brownie mix, pumpkin puree, pumpkin pie spice, and cinnamon in one bowl and stir until completely smooth.
  2. Keep mixing until there are no dry streaks; the batter will be very thick, which is correct.
Add chips (optional)
  1. Fold in the dark chocolate chips if using until evenly distributed.
Bake
  1. Spread the dense batter evenly into the prepared pan using a spatula.
  2. Bake at 350F for 23-26 minutes, until a toothpick comes out clean.
Cool and finish
  1. Cool completely in the pan before cutting so the brownies hold their shape.
  2. Dust with powdered sugar, then cut into 16 bars (each is about 90-100 calories depending on the mix).

Notes

Pro tip: since the batter is thick, press and smooth it firmly for even baking edges. Store airtight at room temperature for up to 3 days or in the refrigerator for up to 5 days; freeze in a sealed container for up to 2 months. If you want a dairy-free option, choose a brownie mix labeled dairy-free and use dairy-free chocolate chips (if desired).
