  • 1 cup natural peanut butter
  • cup honey
  • cup NOW® Sports Creamy Vanilla Whey Protein or NOW® Sports Creamy Vanilla Plant Protein Complex
  • ¼ cup chocolate chips


  • In a large bowl, add the peanut butter, honey, protein powder, and chocolate chips. Stir until well combined.
  • Line an 8x8 pan with parchment or wax paper. Pour the protein mixture into the pan. Press down with your hands to flatten into a relatively even square.
  • Refrigerate for at least 2-3 hours (the mixture will firm up a bit as it chills). Cut into ten bars. Store in the fridge and enjoy as you please!


  • You need natural peanut butter for this recipe - the only ingredients should be peanuts and salt. This is "drippier" than regular peanut butter. If you use regular peanut butter, the mixture may be too dry.
  • Bars will be a little thinner and softer than a store-bought protein bar. If you prefer, you can create a smaller square to form bigger, thicker bars. You can also use this recipe and roll into protein balls instead.
  • Store bars in the fridge for up to 5 days.
