Prepare a 9x13-inch baking pan with a layer of plastic wrap or parchment paper.
Lay down a single layer of ice cream sandwiches in the bottom of the pan.
Evenly distribute half of the whipped cream over the ice cream sandwiches.
Pour half of the fudge sauce over the whipped cream.
Sprinkle half of the crushed cookies and mini chocolate morsels on top of the fudge layer.
Repeat the process with another layer of ice cream sandwiches, followed by the remaining whipped cream, fudge sauce, crushed cookies, and chocolate morsels.
Add sprinkles on top if desired.
Cover the pan tightly with plastic wrap and freeze for a minimum of 4 hours or until solid.
Before serving, let it sit for about 10 minutes to soften slightly, then cut into squares.
