Delicious is the only word that comes to mind when describing these bars. No bake and so easy to make. They are the perfect snack to keep your muscles in anabolic (“growth”) mode and your energy levels on an even keel. Since the bars are relatively high in healthy fat, they make a great daytime snack that can be consumed two or more hours before or after training. For those ultra athletes, these bars may be tolerated during your event, but give them a preliminary try during training to assess performance effects. No matter when you choose to indulge in a Klean Krispy bar, be sure to accompany them with water, seltzer or tea to keep your hydration up to par.

YIELD: 12 servings


  • 1 cup old-fashioned rolled oats
  • ½ cup quick oats (do not process in the food processor)
  • 3 scoops Klean Isolate™ (~1 cup)
  • ½ cup regular or brown rice crispy cereal
  • ½ cup honey
  • ¾  cup peanut butter
  • 2 teaspoons vanilla extract
  • ¼ cup chocolate chips for drizzling


  1.  Line a 9×5” loaf pan with parchment paper or lightly grease with cooking spray.
  2.  Place rolled oats in food processor and pulse until oats are a flour consistency.
  3.  In a medium bowl, mix the rolled oat flour with the quick oats, protein powder, and crispy cereal.
  4. In a small pan over medium heat, stir honey and peanut butter until melted and
    combined. Remove from heat and stir in vanilla extract. Pour peanut butter mixture over oats. Stir well.
  5. Using hands, press mixture into prepared loaf pan.
  6. In microwave, melt chocolate chips for 1 minute, then 30-second intervals, stirring in between, until fully melted. Use a fork to drizzle chocolate over bars.
  7.  Let cool in refrigerator for 30 minutes before slicing into 12 bars.
  8. Store in the refrigerator for maximal yumminess. They will disappear rather quickly, so no worries about spoilage or impaired quality.
