Start by scooping ½ cup of natural creamy peanut butter into a microwave-safe bowl, adding ¼ cup of honey or maple syrup. Heat this mixture in the microwave for 20-30 seconds until warm. Remove it from the microwave and stir until the blend is smooth and well combined.

Next, add in 1 cup of vanilla protein powder, a pinch of salt, and 1 teaspoon of vanilla or almond extract to the smooth mixture. Stir thoroughly until a thick, uniform dough forms.

Gently fold in ½ cup of rainbow sprinkles, ensuring even distribution without allowing the colors to bleed.

Using a tablespoon, scoop out portions of the dough and roll each one into a ball using your hands. Aim for about 1-inch diameter balls.

Place the shaped balls onto a parchment-lined tray, making sure to leave space between each one. Refrigerate the protein balls for at least 20 minutes.

Once firm, store your Birthday Cake Batter Protein Balls in an airtight container in the refrigerator for up to 7 days, or freeze them for longer storage up to 3 months.
