Yes! To freeze, line the Oreo Balls on a baking sheet so they are not touching and flash freeze in the freezer for 30 minutes or until they are hard, this will prevent them from sticking together later.  Transfer to a resealable bag and squeeze out excess or to a freezer safe airtight container.  Freezer for up to 2 months.  Thaw in a single layer the in the refrigerator before serving.
