Instructions

  • Preheat the oven to 350 F and line a 9-inch square baking pan with parchment paper.

Notes

  • Instead of honey you can use agave or maple syrup.
  • Don't want to use sweet potatoes? You can swap it with pumpkin puree or apple sauce.
  • You can use plant-based protein powder, or chocolate protein powder instead of vanilla.
  • Any other nut butter will work. Try cashew butter or almond butter. 
  • peanut butter: You may use creamy peanut butter if you do not want that extra crunchy texture in the brownies. Almond butter will work too.
