This chilly treat may well make your freezer more popular than the neighborhood ice cream truck. The lemony ice cream center is a bright contrast to the surrounding chewy coconut macaroons — and the sandwiches are easily held by eager little hands.
Cooks' notes:
· For a perfectly shaped macaroon, spread coconut mixture in cookie cutter, then lift off cutter. · Ice cream sandwiches can be made 3 days ahead.
