Make these easy, no-bake protein bars at home. They use simple ingredients and provide a satisfying, high-protein snack perfect for meal prep or post-workout fuel.

Ingredients

Scale
  • 1 cup rolled oats
  • 1 cup protein powder (vanilla or unflavored)
  • 1/2 cup natural peanut butter
  • 1/4 cup honey or maple syrup
  • 1/4 cup milk (dairy or non-dairy)
  • 1 teaspoon vanilla extract
  • 1/2 cup dark chocolate chips

Instructions

  1. Line an 8×8 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
  2. In a large bowl, combine the rolled oats and protein powder. Mix them well.
  3. Add the peanut butter, honey or maple syrup, milk, and vanilla extract to the dry ingredients.
  4. Stir everything together until a thick, uniform dough forms. If the mixture is too dry, add milk one teaspoon at a time until it comes together.
  5. Press the dough evenly into the prepared pan. Use the back of a spoon or a spatula to pack it down firmly.
  6. Sprinkle the chocolate chips over the top of the dough. Gently press them into the surface.
  7. Place the pan in the refrigerator and chill for at least 2 hours, or until the bars are firm.
  8. Use the parchment paper overhang to lift the block out of the pan. Cut into 12 even bars.
  9. Store the homemade protein bars in an airtight container in the refrigerator.

Notes

  • For a lower sugar option, use a sugar-free sweetener blend instead of honey or maple syrup.
  • You can substitute peanut butter with almond butter or sunflower seed butter for different flavors.
  • These chewy protein bars hold their shape best when kept cool.
