Make these simple, no-bake protein bars using just five ingredients. They are chewy, satisfying, and perfect for quick meal prep or a healthy on-the-go snack.

Ingredients

Scale
  • 1 cup creamy peanut butter
  • 1/2 cup vanilla or unflavored protein powder
  • 1/2 cup rolled oats
  • 1/4 cup honey or maple syrup
  • 1/4 cup dark chocolate chips (for topping)

Instructions

  1. Line an 8×8 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
  2. In a medium bowl, combine the peanut butter, protein powder, rolled oats, and honey or maple syrup.
  3. Mix all ingredients thoroughly until a thick, uniform dough forms. You may need to use your hands to fully incorporate everything.
  4. Press the mixture evenly into the prepared pan. Press down firmly to make sure the bars hold together well.
  5. Melt the chocolate chips in a microwave-safe bowl in 30-second intervals, stirring until smooth.
  6. Drizzle the melted chocolate over the top of the bar mixture.
  7. Place the pan in the refrigerator and chill for at least 2 hours, or until completely firm.
  8. Use the parchment overhang to lift the block out of the pan. Cut into 10 even bars.
  9. Store your homemade protein bars in an airtight container in the refrigerator.

Notes

  • For a vegan option, use maple syrup instead of honey and ensure your protein powder is plant-based.
  • If the mixture seems too dry, add one teaspoon of water or milk at a time until it binds.
  • These bars taste best when kept cold, making them excellent for your next meal prep session.
