Ingredients Method Notes

Ingredients
  

Main Ingredients
  • 1 cup Natural creamy peanut butter Use smooth, natural peanut butter for the best texture.
  • 3 tablespoons Honey or maple syrup Maple syrup can be used for a vegan version.
  • 2 scoops Vanilla protein powder Approximately 50g.
  • 1 tablespoon Rainbow sprinkles Use nonpareil or sugar-based sprinkles to minimize bleeding.
  • 1 pinch Salt
  • 1/4 teaspoon Vanilla or almond extract

Method
 

Preparation
  1. Combine peanut butter and honey in a microwave-safe bowl. Heat for 20–30 seconds, then stir until completely smooth.
  2. Stir in the vanilla protein powder, salt, and extract. Mix until a thick, pliable dough forms. If too dry, add a teaspoon of milk; if too wet, add more protein powder.
  3. Gently fold in the rainbow sprinkles so the colors don’t bleed.
  4. Scoop one tablespoon of dough at a time and roll between your palms to form a smooth ball.
  5. Optional: Roll the finished balls in extra sprinkles for more color.
  6. Place the balls on a parchment-lined tray and refrigerate for at least 20 minutes before eating to allow them to firm up.

Notes

Store in an airtight container in the refrigerator for up to 10 days. For longer storage, freeze in a single layer then transfer to a freezer-safe bag for up to 3 months. Thaw in the fridge before eating. For the best consistency, measure protein powder by weight.
