Prepare the base layer: Lay 6 ice cream sandwiches in the bottom of a 9×13-inch baking dish, side by side. Make sure the sandwiches fit snugly to form a complete layer.

1. Spread the whipped cream: Spread half of the whipped cream or whipped topping evenly over the ice cream sandwiches.
2. Add toppings: Drizzle the hot fudge sauce and caramel sauce over the whipped cream layer for extra flavor (optional). You can also sprinkle a bit of crushed cookies, chocolate chips, or sprinkles at this point to add texture and flavor.
3. Repeat the layers: Lay the remaining 6 ice cream sandwiches on top of the whipped cream layer. Spread the remaining whipped cream on top, smoothing it out with a spatula.
4. Add final toppings: Finish the dessert by sprinkling the top with crushed Oreos, chocolate chips, or sprinkles. If you like, you can drizzle more hot fudge and caramel sauce for a finishing touch.
5. Chill the cake: Cover the dish with plastic wrap and freeze the cake for at least 4 hours or overnight until it is firm and set.
6. Serve: When ready to serve, slice the cake into squares, and enjoy this cool, creamy dessert!
