Add rolled oats to a food processor along with the whey protein powder; pulse until smooth. Skip this step if you are using oat flour. Add the ingredients to a small mixing bowl or the bowl of your stand mixer.

Next, add the nut butter, cream cheese and maple syrup. Mix until smooth. Fold in sprinkles at the end.

Roll the mixture into bite-size balls or press it into an 8×8-inch baking sheet lined with parchment paper.

Combine Greek yogurt and powdered sugar in a small bowl. Add meringue powder if using. Sweeten with honey.

Drizzle glaze over protein bites or pour over protein bars.
