  • ¼ cup vanilla protein powder (I used Nuzest)
  • 1 cup oat flour
  • ¼ teaspoon salt omit if peanut butter has salt
  • ½ cup natural creamy peanut butter that’s drippy or almond butter
  • ¼ cup honey
  • 1 Tablespoon melted coconut oil (to help moisten) more if needed
  • 1 teaspoon vanilla
  • 2-4 Tablespoons chocolate chips plus extra chocolate chips for topping


  • Line a loaf pan with parchment paper.

  • Add in peanut butter, honey, vanilla and coconut oil. The dough will be quite thick. I suggest combining the dough with your hands. If it’s still too dry add more coconut oil, 1 teaspoon at a time.

  • Let bars chill in fridge for at least one hour before cutting.
  • Remove bars from the fridge, cut into 6 equal-sized bars and enjoy.
  • Bars will last about one week in the fridge or up to 3 months in the freezer.



  • Honey: I haven't tested this recipe with anything else, but I think another liquid sweetener like maple syrup or date syrup would work well. 
  • Peanut butter: any natural, drippy nut butter should work. You can try almond butter, cashew butter or sunflower seed butter.
