Once cookies have fully cooled, place one to two scoops of ice cream on half of the bottom side of the cookies. Press the bottom side of each of the remaining cookies onto the ice cream scoops to form sandwiches. Use your finger or a knife to spread the ice cream evenly around the sides of each sandwich. Wrap the sandwiches individually in plastic wrap or place in a large dish and cover. Freeze at least 30 minutes before decorating. Place patriotic sprinkles in a shallow dish. Remove sandwiches from freezer and roll each sandwich in the sprinkles until covered as desired. Enjoy!
