Recipe for Protein Bars with Peanut Butter


  • 1 cup natural peanut butter
  • 1/2 cup honey or maple syrup
  • 1 1/2 cups rolled oats
  • 1 cup protein powder (vanilla or chocolate)
  • 1/2 cup mini chocolate chips (optional)
  • 1/4 cup chia seeds or flaxseeds
  • 1/4 cup unsweetened shredded coconut (optional)
  • 1 teaspoon vanilla extract


  1. Prepare the Pan: Line an 8×8-inch baking pan with parchment paper, leaving some overhang for easy removal.
  2. Mix Wet Ingredients: In a microwave-safe bowl, combine the peanut butter and honey. Microwave for 30-45 seconds until warm and easily stirrable. Add the vanilla extract and mix well.
  3. Combine Dry Ingredients: In a large bowl, mix the rolled oats, protein powder, chia seeds, and shredded coconut. Add the wet ingredients to the dry mixture and stir until well combined.
  4. Add Chocolate Chips: If using, fold in the mini chocolate chips until evenly distributed.
  5. Press into Pan: Transfer the mixture to the prepared baking pan. Use a spatula or your hands to press the mixture firmly and evenly into the pan.
  6. Chill: Refrigerate the bars for at least 2 hours, or until firm. Once set, use the parchment overhang to lift the bars out of the pan and cut them into desired sizes.
  7. Store: Store the protein bars in an airtight container in the refrigerator for up to two weeks.

Tips and Variations

Flavor Variations

  • Chocolate Lovers: Add 2 tablespoons of cocoa powder to the dry ingredients for a chocolatey twist.
  • Nutty Delight: Mix in 1/4 cup of chopped nuts like almonds or walnuts for extra crunch.
  • Fruit Infusion: Incorporate 1/4 cup of dried fruit such as cranberries, raisins, or apricots for a touch of sweetness.

Dietary Adjustments

  • Vegan Option: Use maple syrup instead of honey and plant-based protein powder.
  • Gluten-Free: Ensure the rolled oats and protein powder are certified gluten-free.
