Unwrap the candy bars and cut them into bite-sized pieces. Set them aside.
Cover a 9x15 cookie sheet with aluminum foil.
Lay graham crackers next to each other so that they fit snug and cover most of the cookie sheet.
Pour Dulce de leche into a microwave-safe dish and microwave for 30 seconds, stir the mixture, and microwave again for another 30 seconds.
Spread the caramel over the graham crackers using an offset spatula or small knife. Be sure to spread the caramel all the way to the edges.
Place chocolate chips into a microwave-safe dish, microwave for 30 seconds, stir, microwave again for another 30 seconds.
Pour the melted chocolate over the caramel and spread it all the way to the edges covering the caramel.
Sprinkle the cut-up candy bars on top of the chocolate.
Refrigerate for 2-3 hours.
To slice, lift the foil out of the cookie sheet, place it on a large cutting board, and slice it into pieces.
