Key Ingredients

Here’s what you’ll need to make these no-bake peanut butter protein bars:

• Peanut Butter: Natural and creamy works best. Adds protein, flavor, and healthy fats.
• Protein Powder: Vanilla or chocolate protein powder gives structure and extra protein.
• Oats or Almond Flour: Creates the chewy base. Use oats for a classic texture or almond flour for low-carb.
• Honey or Sugar-Free Syrup: Adds sweetness and helps bind the bars.
• Coconut Oil: Keeps them soft and adds a subtle flavor.
• Vanilla Extract: Enhances the peanut butter taste.
• Dark Chocolate Chips (Optional): For a chocolate-peanut butter combo.
