Place 8 ice-cream sandwiches in a 13- x 9-inch baking dish. Spread caramel sauce evenly over sandwiches. Sprinkle evenly with 1 cup pecans. Top with remaining ice-cream sandwiches. Spread whipped topping evenly over sandwiches. Sprinkle with remaining 1/4 cup pecans. Cover and freeze at least 1 hour. Let stand 5 minutes before serving; cut into squares. Drizzle with warm hot fudge sauce.
Took this to a friends house for dessert and they raved about it! Thought I had made the individual layers--couldn't believe it was as easy as layering ice cream sandwiches! Will absolutely make again!
Wonderful and easy make ahead recipe. It is just as delicious with toasted walnuts in place of toasted pecans. You can't go wrong either way. I usually add extra nuts because I think they are what makes this dessert special.
