Ingredients

Scale

Main Ingredients

  • 1 ½ cups creamy no-stir peanut butter
  • ¾ cup protein powder (vanilla or chocolate)
  • ¼ cup honey or maple syrup
  • 1 cup rolled oats
  • ¼ cup dark chocolate chips
  • Optional: Sea salt for topping

Instructions

  1. Make the Peanut Butter Base: In a large bowl, mix together the peanut butter, protein powder, honey (or maple syrup), and oats until well combined. The mixture will be thick but should hold together easily.
  2. Press into the Pan: Line an 8×8-inch baking dish with parchment paper. Press the peanut butter mixture evenly into the bottom of the dish to form a compact layer.
  3. Melt the Chocolate: In a microwave-safe bowl, melt the dark chocolate chips in 30-second increments, stirring after each until smooth. Pour the melted chocolate over the peanut butter layer and spread it out evenly with a spatula.
  4. Chill: Place the dish in the refrigerator for at least 1 hour to allow the chocolate to set and the bars to firm up.
  5. Slice & Serve: Once the chocolate is fully set, slice the bars into 12 to 16 pieces. Store in an airtight container in the fridge for up to one week or freeze for longer storage.

Notes

  • Use no-stir peanut butter for easier mixing and smoother texture.
  • Choose your preferred protein powder flavor to customize the bars.
  • Honey and maple syrup are interchangeable; use based on dietary preference or sweetness level.
  • Adding a sprinkle of sea salt on top before chilling enhances the chocolate flavor.
  • For firmer bars, you can freeze them for 30 minutes before slicing.
  • These bars are best stored refrigerated to maintain freshness and texture.
