How to Make These Irresistible Birthday Cake Batter Protein Balls

Making these yummy little bites is a breeze. Ready? Let’s get cooking!

Combine Peanut Butter and Honey : In a microwave-safe bowl, mix 1 cup of creamy peanut butter and 3 tablespoons of honey. Microwave for 20–30 seconds until warm (not hot!), then stir until completely smooth.
Add the Good Stuff : Stir in 2 scoops of vanilla protein powder, a pinch of salt, and 1/4 teaspoon of your chosen extract. Mix until you get a thick, pliable dough. If it’s too dry, add a teaspoon of milk; if it’s too sticky, sprinkle in a bit more protein powder.
Fold in the Sprinkles : Gently fold in 1 tablespoon of rainbow sprinkles with a spatula, being careful not to let the colors bleed. We want those vibrant specks to shine!
Shape the Dough : Scoop about 1 tablespoon of dough at a time and roll it between your hands to form a smooth ball. It’s a bit like playing with playdough but way yummier!
Optional: Extra Sprinkles : For an even brighter appearance, roll those finished balls in some extra sprinkles! It’s all about that presentation, right?
Chill Out : Place your protein balls on a parchment-lined tray and refrigerate for at least 20 minutes to firm up. This step is crucial, don’t skip it!
