Ingredients

Egg Replacer

  • 2 tablespoons peanut butter
  • 2 tablespoons ground chia seeds
  • 8 tablespoons water

Brownie Batter

  • 18 oz package brownie mix any brand, any flavor as long as it's dairy-free and egg-free
  • ¼ teaspoon baking powder
  • cup vegetable oil
  • 2 tablespoons water
  • Optional: Add chocolate chips to the batter or sprinkle on top of the brownies before baking.

Instructions

  • Preheat oven to 325°F/163°C. Line a 9x9 inch pan or an 8x8 inch pan (for thicker brownies) with parchment paper. Spray with vegetable cooking spray.
  • Heat peanut butter in a microwave-safe bowl for 15 to 20 seconds, until softened.
  • Add ground chia seeds and water to a separate bowl. Stir to combine. Add the softened peanut butter and stir together.
  • Pour the brownie mix to a bowl. Add the baking powder and stir to combine.

  • Let the brownies cool in the pan. For cleaner slices, refrigerate for 30 minutes before slicing.

Notes

I recommend using creamy peanut butter to replace the fat removed with the vegetable oil. You can substitute almond butter.
