Transfer the mixture to a bowl, then cover and refrigerate for at least 30 minutes. With a spoon or cookie scoop
, scoop the mixture then roll it into balls. Transfer to an airtight container and store in the refrigerator for up to 2 weeks or freeze for up to 2 months. If the balls are frozen, there is no need to let thaw—just eat immediately, or let them sit a few minutes to warm up if desired.
