INGREDIENTS

• Peanut Butter : Natural creamy peanut butter provides flavor, healthy fats, and helps bind the bars together.
• Honey : Honey adds natural sweetness while helping create the chewy texture.
• Vanilla Extract : A small amount enhances the overall flavor.
• Rolled Oats : Use certified gluten-free oats if needed. Oats provide structure and make the bars more satisfying.
• Vanilla Protein Powder : I used Redmond Roots Vanilla Protein Powder, which adds protein while contributing a subtle sweetness.
• Sea Salt : Just enough to balance the sweetness and enhance the peanut butter flavor.
• Optional : Chocolate chips. Perfect if you’d like a little chocolate in every bite. Please note this will change the nutrition facts.

EQUIPMENT

• Large Mixing Bowl
• Silicone Spatula
• Measuring Cups and Spoons
• 8×8 – inch Baking Dish or Loaf Pan
• Unbleached Parchment Paper

STEP-BY-STEP INSTRUCTIONS

1. Prepare the Pan. Line an 8×8-inch baking dish or loaf pan with parchment paper.
2. Warm the Peanut Butter and Honey. In a microwave-safe bowl (or in a saucepan on the stovetop), gently warm the peanut butter and honey. You want it to be smooth and fully combined when you stir.
3. Add the Vanilla. Mix in the vanilla extract.
4. Add the Dry Ingredients. Add the rolled oats, protein powder, and sea salt. Stir until a thick dough forms.
5. Adjust the Consistency. Add water one tablespoon at a time until the mixture easily holds together when pressed between your fingers. You may not need any!
6. Add Chocolate Chips (Optional). Fold in chocolate chips if using.
7. Press Into Pan. Transfer the mixture to the prepared pan. Press firmly into an even layer.
8. Chill. Refrigerate for at least one hour.
9. Slice and Serve. Cut into 12 bars and enjoy.

EXPERT TIPS FOR SUCCESS

• Use natural peanut butter that has been stirred well. The only two ingredients should be peanuts and salt.
• Press the mixture firmly into the pan to prevent crumbling.
• Chill completely before slicing.
• For clean cuts, use a sharp knife wiped clean between slices.
• Store bars cold for the best texture.
• Want to increase the protein? You can add an extra scoop of protein powder and a little additional water as needed, or simply cut the bars into larger portions. Keep in mind that any changes to the recipe or serving size will affect the nutrition information listed in the recipe card.

STORAGE INSTRUCTIONS

• Refrigerator. Store in an airtight container for up to 1 week.
• Freezer. Freeze in a sealed container for up to 3 months. Place parchment paper between bars to prevent sticking. Allow bars to thaw for a few minutes before serving.
