Notes

  • Want to increase the protein? You can add an extra scoop of protein powder and a little additional water as needed, or simply cut the bars into larger portions. Keep in mind that any changes to the recipe or serving size will affect the nutrition information listed in the recipe card.
  • Certified gluten-free oats recommended if needed.
  • Add water gradually as protein powders absorb moisture differently.
  • Optional chocolate chips add extra sweetness and texture.
  • Store chilled for best results.
