Nothing conjures up childhood nostalgia like these frozen sandwiches - but forget the jangling bells on the ice cream truck and make your own for an even better treat. The ice cream needs to be firm enough to hold its shape before making the sandwiches. If it's too soft, let it chill in the freezer before assembling, but if it's too hard, let it sit out for a few minutes first.
Make Ahead Tip: Store wrapped sandwiches in the freezer for up to 1 month.
