Yes, you can make a vegan brownie from a box mix! Just read the label to make sure the ingredients are vegan compliant.  Then replace your egg with aquafaba (bean juice) a powdered egg replacer, and mashed potatoes. This recipe also used tahini paste instead of oil
Print Recipe


  • 1 box Duncan Hines Brownie Mix
  • 3 Tablespoons Bob's Red Mill Egg Replacer
  • 1/2 cup dehydrated potato flakes
  • 9 Tablespoons aqufaba This is the liquid from a can of garbanzos beans.
  • 1/2-3/4 cup water see note - 1 1/4 cup liquid in all
  • 1/3 cup tahini paste
  • 1/2 cup vegan chocolate chips


  • Preheat oven to 350°
  • Prepare a 9x9" or 7x11" baking pan with cooking spray.
  • Drain and save the liquid from a can of garbanzo beans.  This will be a little over 1/2 cup. You will use 1 1/4 cup total liquid.  Add water to the aquafaba (bean juice) to make 1 1/4 cup total.  This will be a little less than 3/4 cup water. 
  • With an electric mixer, mix all ingredients together except for chocolate chips.
  • Mix in chocolate chips.
  • Turn into prepared pan. Sprinkle chocolate chips on top. 
  • Cook in a 350° oven for 27-35 minutes or until brownies are just pulling away from sides and center springs back slightly when touched. Be careful not to overcook. Because of the aquafaba, these brownies will be a little moister than brownies made with eggs and might not look done.


You will be using a total of 1 1/4 cup liquid in this recipe.  Measure out the aquafaba first into a large glass measuring cup and then fill will water up to the 1 1/4 line.  This will be between 1/2 - 3/4 cup water.
