Ingredients

Scale

Wet Ingredients

  • 1 cup natural creamy peanut butter
  • 3 tablespoons honey or maple syrup
  • 1/4 teaspoon vanilla or almond extract

Dry Ingredients

  • 2 scoops (50g) vanilla protein powder
  • 1 pinch salt

Add-ins

  • 1 tablespoon rainbow sprinkles

Instructions

  1. Heat Peanut Butter and Sweetener: Combine the natural creamy peanut butter and honey or maple syrup in a microwave-safe bowl. Heat for 20 to 30 seconds until warm, then stir well until the mixture is completely smooth and well combined.
  2. Mix in Protein Powder and Flavorings: Add the vanilla protein powder, a pinch of salt, and the vanilla or almond extract to the peanut butter mixture. Stir thoroughly until a thick, pliable dough forms. If the dough feels too dry, add a teaspoon of milk to loosen it; if too wet, add a little more protein powder to thicken.
  3. Fold in Sprinkles: Gently fold in the rainbow sprinkles to distribute them without causing the colors to bleed into the dough, maintaining a vibrant appearance.
  4. Shape into Balls: Using a tablespoon-sized scoop, portion out the dough and roll each scoop between your palms to form smooth, round balls.
  5. Optional – Coat with Extra Sprinkles: For an even more festive look, roll the finished balls in additional rainbow sprinkles to coat their exterior.
  6. Chill to Set: Arrange the protein balls on a parchment-lined tray and refrigerate for at least 20 minutes. This step allows the protein balls to firm up and hold their shape for serving.

Notes

  • Adjust the consistency of the dough with milk or protein powder as needed to make rolling easier.
  • Use plant-based protein powder to make this recipe vegan-friendly.
  • Store protein balls in an airtight container in the refrigerator for up to one week.
  • These protein balls are a great pre- or post-workout snack to boost protein intake.
  • You can substitute peanut butter with almond or cashew butter for a different nutty flavor.
