Step 1

Microwave the fudge and caramel topping for about 15-20 seconds to loosen it and make it spreadable, if necessary.

Step 2

Line the bottom of a 9x13 baking dish with a layer of the ice cream bars (10 of them; trim if necessary.)

Step 3

Spread half of the hot fudge, followed by the caramel, and then Cool Whip over the sandwiches. Sprinkle on half of the chocolate chips and toffee pieces. Repeat layers.

Step 4

Freeze until firm, about 1 hour. Cut into squares and serve.
