Fold the crushed cookies into the whipped topping and set aside.
Place 2 1/2 Klondike Ice Cream Sandwiches in the bottom of the prepared pan.
Spread 1/4 cup of fudge sauce over top of the ice cream sandwiches.
Spread half of the whipped topping mixture over the fudge sauce.
Top with 2 1/2 additional Klondike Ice Cream Sandwiches, followed by the remaining fudge and then the remaining whipped topping mixture.
Sprinkle with additional crushed cookies, if desired.
Cover and freeze for 2 hours, or until firm.
Cut and serve! Enjoy!
