Ingredients

1 cup natural creamy peanut butter
3 tablespoons honey or maple syrup
2 scoops (about 50 g) vanilla protein powder
1 tablespoon rainbow sprinkles (plus more for rolling)
Optional: pinch of salt
Optional: splash of vanilla extract or almond extract

Instructions

Step 1: In a microwave-safe bowl, combine the peanut butter and honey. Microwave for 20–30 seconds, then stir until the mixture is smooth.
Step 2: Stir in the vanilla protein powder until a dough forms. If needed, adjust the consistency by adding a little milk or extra protein powder.
Step 3: Gently fold in the rainbow sprinkles to evenly distribute them throughout the mixture.
Step 4: Scoop out tablespoon-sized portions and roll them into balls. Roll each ball in extra sprinkles if you like for a festive finish.
Step 5: Place the protein balls on a parchment-lined tray and refrigerate for 20 minutes before serving to help them firm up.

Tips & Variations

For added flavor, try a splash of almond or vanilla extract. A pinch of salt can also enhance the sweetness.
Use your favorite nut butter if you want a different taste, such as almond or cashew butter.
If the mixture feels too sticky, chill it briefly before rolling to make handling easier.

Storage

Store the protein balls in an airtight container in the refrigerator for up to one week. You can also freeze them for up to one month. Let thaw in the fridge before enjoying. Reheat is not necessary, as they are delicious chilled.

Main Ingredients

1 cup natural creamy peanut butter
3 tablespoons honey or maple syrup
2 scoops (about 50 g) vanilla protein powder
1 tablespoon rainbow sprinkles (plus more for rolling)
Optional: pinch of salt
Optional: splash of vanilla extract or almond extract

Instructions

Combine peanut butter and honey: In a microwave-safe bowl, add the peanut butter and honey. Microwave for 20–30 seconds to soften, then stir until smooth and well blended.
Mix in protein powder: Add the vanilla protein powder to the peanut butter mixture and stir thoroughly until a dough forms. If the dough is too thick, add a small splash of milk; if too thin, add a bit more protein powder to reach the right consistency.
Fold in sprinkles: Gently fold the rainbow sprinkles into the dough, distributing them evenly without overmixing to avoid color bleeding.
Form balls: Use a tablespoon size scoop to portion the dough and roll each portion between your hands into a smooth ball. Roll the balls in extra sprinkles to coat if desired.
Chill before serving: Place the balls on a parchment-lined tray and refrigerate for at least 20 minutes to firm up before serving.

Adjust sweetness by varying the amount of honey or maple syrup.
Add a pinch of salt to enhance flavor if using unsalted peanut butter.
