Make simple, chewy peanut butter protein bars at home with only five ingredients. These no-bake bars are perfect for quick meal prep and satisfy cravings.

Ingredients

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

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 rolled oats, protein powder, peanut butter, maple syrup, and milk.
  3. Mix all ingredients thoroughly until a thick, uniform dough forms. If the mixture is too dry, add milk one teaspoon at a time until it comes together.
  4. Press the dough evenly into the prepared pan, using the back of a spoon or your fingers to compact it firmly.
  5. If using chocolate, melt the chocolate chips in a microwave-safe bowl in 30-second intervals, stirring until smooth. Drizzle the melted chocolate over the top of the bars.
  6. Place the pan in the refrigerator and chill for at least 1 hour, or until firm.
  7. Lift the bars out using the parchment paper overhang and cut into 10 even squares. Store in an airtight container in the refrigerator.

Notes

  • For a vegan option, use maple syrup instead of honey and use non-dairy milk.
  • If you prefer a firmer bar, reduce the liquid slightly.
  • These bars store well in the refrigerator for up to one week.
