Ingredients
 

  • ⅔ cup natural peanut butter
  • ¼ cup honey
  • 1¼ cup vanilla whey protein powder
  • ⅓ cup almond flour
  • 1 tbsp ground flax
  • 2 tbsp almond milk
  • 2 tbsp chocolate chips
  • 1 pinch sea salt

Chocolate Topping

  • ¼ cup chocolate chips
  • 1 pinch flake salt

Equipment

  • 1 loaf pan

Instructions
 

  • In a medium bowl, stir together peanut butter and honey until smooth and combined.
  • Add whey protein powder, almond flour, ground flax, and salt. Mix until a thick dough forms.
  • If mixture feels too dry, add almond milk 1 tablespoon at a time until dough holds together.
  • Line a loaf pan (or small square pan) with parchment paper.
  • Press mixture firmly and evenly into the pan. Compress well to prevent crumbling.
  • Melt dark chocolate chips in the microwave in 20-second intervals, stirring between each.
  • Spread melted chocolate evenly over the top.
  • Sprinkle with flaky sea salt if desired.
  • Refrigerate for 1–2 hours until fully set.
  • Slice into 8 bars and store in the refrigerator.

Notes

  • Protein powder brands vary, adjust almond milk as needed.
  • If bars are too sticky, add more almond flour.
  • If too dry, add 1 tablespoon additional nut butter.
  • Store in refrigerator up to 7 days or freeze up to 3 months.
  • For dairy-free option, use plant-based protein powder.
