How to Make Birthday Cake Batter Protein Balls
Ingredients:
- 1 cup natural creamy peanut butter
- 3 tablespoons honey or maple syrup
- 2 scoops (50g) vanilla protein powder
- 1 tablespoon rainbow sprinkles
- 1 pinch salt
- 1/4 teaspoon vanilla or almond extract
Directions:
- Start by combining the peanut butter and honey in a microwave-safe bowl. Heat it in the microwave for 20–30 seconds, then stir until the mixture is completely smooth.
- Next, stir in the vanilla protein powder, salt, and extract. Mix everything together until you form a thick, pliable dough. If the dough is too dry, you can add a teaspoon of milk; if it’s too wet, sprinkle in a little more protein powder.
- Gently fold in the rainbow sprinkles. Be careful not to mix too vigorously, or the colors may bleed.
- Scoop one tablespoon of dough at a time and roll it between your palms to create a smooth ball.
- If you want, roll the finished balls in extra sprinkles for more color.
- Place the balls on a parchment-lined tray and refrigerate for at least 20 minutes before eating. This helps them firm up and makes them easier to enjoy!
