In a large bowl, combine oats, Rice Krispies, peanut butter, honey, and vanilla extract.
Mix until all dry ingredients are thoroughly coated. Optionally, add a handful of chocolate chips and marshmallows, continuing to mix to distribute them evenly throughout the mixture.
Using a cookie scoop or your hands, take portions of the mixture and roll them into balls.
Place the balls on a greased pan and refrigerate for about 1 hour to set, ensuring they hold their shape.
Once set, transfer the protein bites to an airtight container for storage.
Enjoy these delightful protein-packed snacks throughout the week!
