If you want to go one step further and make the ice cream sandwiches extra festive, you can roll them in things like crushed candy, mini chocolate chips (any flavor), sprinkles, or any crushable other little sweet item you fancy. Or, if you want to go for the salty-sweet vibe, think about crushed nuts, pretzels, or potato chips. This is also a nice project for the kids to help out with. Just put the crushed item on a plate, and roll the ice cream sandwiches sideways until the ice cream is coated. Place the ice cream sandwiches on a plate back in the freezer until they firm up.
