For best texture, keep the protein balls chilled and only let them sit at room temperature for a few minutes before eating so they stay firm but not hard; if the mixture feels too sticky when rolling, lightly dampen your hands or chill the bowl for 10 minutes before shaping, and if it feels too dry, a splash more milk or a bit of extra peanut butter will help bind it. You can swap peanut butter for almond or cashew butter, choose a protein powder you like the taste of since it strongly affects the flavor, and use mini chocolate chips so they distribute evenly. These keep well in the fridge for up to one week or in the freezer for about one month, and freezing them on a tray before transferring to a container prevents sticking.
