Chewy, protein-packed granola bars made with oats, protein powder, and peanut butter for a quick healthy snack.
Prep Time 2 minutes
Cook Time 5 minutes
Total Time 7 minutes
Servings: 20 servings

Ingredients
  

  • 3 cups rolled oats
  • 1 1/2 cups protein powder See notes for recommended types
  • 1 cup peanut butter smooth and creamy
  • 1/2 cup honey or brown rice syrup see notes
  • 1/2 cup chocolate chips optional

Equipment

  • 8 x 8-inch baking pan
  • Parchment Paper
  • Large mixing bowl
  • Microwave-safe Bowl
  • Whisk or spoon
  • Spatula or spoon for pressing
  • Measuring Cups

Method
 

  1. Line an 8 x 8-inch pan with parchment paper and set it aside.
  2. In a large bowl, combine the rolled oats and protein powder until evenly mixed.
  3. Place the peanut butter and honey (or brown rice syrup) in a microwave-safe bowl and heat in 20-second intervals, stirring between intervals, until the peanut butter softens and the mixture is smooth and thick.
  4. Pour the warm peanut butter mixture into the dry ingredients and stir until fully combined. If using chocolate chips, fold them in at the end.
  5. Transfer the mixture to the prepared pan and press it firmly and evenly into the pan so the surface is smooth.
  6. Refrigerate for at least 1 hour to firm up, then lift the mixture from the pan using the parchment and slice into 20 bars.

Notes

  • If the mixture is too thick, add a few tablespoons of water to loosen it.
  • Use vanilla or plain protein powder; brown rice, casein, or some whey blends work well.
  • Almond butter or a nut-free alternative can be used instead of peanut butter.
  • Maple syrup can be substituted but may not hold as well.
  • Store bars in the refrigerator covered for up to 4 weeks.
  • Freeze individually wrapped bars for up to 6 months.
