Preheat oven to 350° F. Line a 13 x 9″ pan with foil, with ends of foil extending over sides of pan; spray with cooking spray paying special attention to corners of the pan and where the bar edges will touch the foil along the sides.
Arrange 24 crackers, salt side down, in single layer on the bottom of prepared pan, knocking off the corner of four crackers to fit in the corners of the pan. Crush remaining crackers and set aside to sprinkle on bars before the condensed milk goes on.
Reserve 1/4 cup chocolate chips to use as a topping later. Sprinkle the remainder on top of cracker layer in pan. Top with the crushed crackers. Pour condensed milk evenly over ingredients in pan.
Bake 25 to 30 minutes. or until lightly browned. Turn pan front to back at about 20 minutes so it browns evenly. Remove from oven and cool completely.
Once bars are cool, melt the reserved 1/4 cup chocolate chips. This can be done in a double boiler but it’s easier to just put chips in a small bowl and microwave for 30 seconds. Stir and if chocolate isn’t completely melted, place back in microwave and go for another 30 seconds. Let cool until easy to handle. Transfer to a Ziploc bag, snip off a small corner at the bottom.
Remove bars from pan using the foil “handles.” Pipe chocolate across the cooled bars. Cut into bars or break into reasonably sized pieces after the chocolate drizzle has hardened.
