This is for Mary in Texas. A very favorite dessert in our family and so easy. I only make one layer of sandwiches which is plenty for a serving instead of the double layer.

Unbelievably Fast & Mysterious Ice Cream Cake

24 ice cream sandwiches (any brand) ( I only use 12 sandwiches)
1 (8 oz.) container Cool Whip (may take more depending on how much you like)
1 (1 oz.) pkg. Toffee bits or 2 Heath bars (freeze & crush bars if used)
(bits are better) OR malted milk balls, crushed with rolling pin in a
plastic bag.
2 (1.25 oz.) Hershey bars or 1 large (freeze chop or grate)
Chocolate fudge sauce (if desired)

Arrange 12 ice cream sandwiches on bottom of 13 x 9-inch glass dish. Spread half of Cool Whip on top of bars. Sprinkle 1/3 to 1/2 cup toffee bits on top, sprinkle 1 Hershey bar (chopped) on top, then start again with ice cream sandwiches, Cool Whip, toffee bits, and chocolate bits. Put in freezer and fast freeze, then cover with plastic wrap or foil. Leave in freezer until ready to serve. Best if made day before serving. When ready to serve, you may drizzle with fudge sauce (barely heated) if desired. Refreeze leftovers.
