Third layer- half of Butterfinger bars, and drizzle half of chocolate and caramel syrup
Fourth layer- rest of the ice cream sandwiches
Fifth layer- rest of the Cool Whip
Sixth layer - rest of the Butterfinger, caramel, and chocolate
Freeze at least 2 hours.
Notes
This makes a 9 x 13 pan. Also, you can change it up a little by using your favorite candy bars instead using the Butterfingers recommended in the recipe.
