Make these simple, chewy homemade protein bars with only five ingredients. They require no baking and are perfect for quick meal prep or a satisfying, high-protein snack.

Ingredients

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

Instructions

  1. Line an 8×8 inch baking dish with parchment paper, leaving an overhang for easy removal.
  2. In a large bowl, combine the rolled oats, peanut butter, protein powder, 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 baking dish. Press down firmly to make sure the bars hold their shape.
  5. Place the dish in the refrigerator to chill for at least 1 hour, or until firm.
  6. Once chilled, lift the bars out using the parchment paper overhang. Cut the block into 10 to 12 equal bars.
  7. Melt the chocolate chips in a microwave-safe bowl in 30-second intervals, stirring until smooth.
  8. Drizzle the melted chocolate over the tops of the bars.
  9. Return the bars to the refrigerator for 10 minutes to allow the chocolate to set before serving.

Notes

  • For a vegan option, substitute maple syrup for honey.
  • If the mixture seems too dry, add one teaspoon of water or milk at a time until it comes together.
  • Store your finished protein bars in an airtight container in the refrigerator for up to one week, or freeze them for longer storage.
  • You can substitute peanut butter with almond butter or sunflower seed butter for variety.
