  • Total Time: 1 hour 15 minutes (including chilling time)
  • Yield: 16 bars 1x

Ingredients

Scale
  • 1 cup rolled oats
  • 1 cup natural peanut butter (creamy or crunchy)
  • 1/2 cup honey or maple syrup
  • 1/2 cup protein powder (chocolate or vanilla)
  • 1/4 cup cocoa powder
  • 1/2 cup dark chocolate chips (plus extra for topping)
  • 1/4 teaspoon salt
  • 1 teaspoon vanilla extract

Instructions

  1. Prepare the Pan: Line an 8×8-inch baking dish with parchment paper, leaving some overhang for easy removal.
  2. Mix Dry Ingredients: In a large mixing bowl, combine the rolled oats, protein powder, cocoa powder, and salt. Stir until well mixed.
  3. Combine Wet Ingredients: In another bowl, mix the peanut butter, honey (or maple syrup), and vanilla extract until smooth and well combined.
  4. Combine Mixtures: Pour the wet mixture into the dry ingredients and stir until everything is evenly combined. The mixture should be thick and sticky. If desired, fold in the dark chocolate chips.
  5. Press into Pan: Transfer the mixture to the prepared baking dish. Use a spatula or your hands to press it down firmly and evenly.
  6. Chill and Set: Refrigerate the mixture for at least 1-2 hours to allow it to firm up.
  7. Cut and Serve: Once set, lift the bars out of the pan using the parchment paper. Cut into squares or rectangles. If desired, melt additional chocolate chips and drizzle over the top before cutting.
  8. Store: Store the bars in an airtight container in the refrigerator for up to one week.
