For each sandwich, place about 1/3 cup ice cream in center of 1 caramel-topped cookie; flatten slightly. Place second cookie, caramel side down, on ice cream. Gently press cookies together in center to form ice cream sandwich; ice cream should spread to edge of cookies. Gently roll ice cream edge of sandwich in chocolate sprinkles. Quickly wrap sandwich in foil; immediately place in freezer. Freeze at least 2 hours or until firm. Let stand 5 to 10 minutes before serving.
