Twix Ice Cream Sandwich Cake

boxes regular sized ice cream sandwiches (12 count)

hot fudge sauce (Homemade is good but store bought is fine!)

butterscotch caramel sauce (homemade is good, but a 17 ounce container of store bought is fine, too!)

heavy cream (whipping)

king sized Twix bars (*See Notes, frozen for at least 30 minutes, then smashed with something heavy to break them while still in their wrappers)

Also helpful but not strictly necessary:

heavy duty aluminum foil
