Make these easy, no-bake protein bars using only five simple ingredients. They are chewy, satisfying, and perfect for quick meal prep or a healthy snack when you need sustained energy.

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 compact the bars.
  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 1 hour, or until firm.
  8. Use the parchment overhang to lift the block out of the pan. Cut into 10 even bars.
  9. Store the bars in an airtight container in the refrigerator for up to one week.

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 comes together.
  • These homemade protein bars taste best when kept chilled.
