Line cookie sheet with foil and grease. Cover with 35 unsalted saltine crackers. Bring to a boil and simmer 3 minutes 1 cup sugar and 1 cup butter. Pour over crackers and bake at 400 degrees for 5 minutes.
Remove from oven and while hot spread with a 12-ounce package of chocolate bits. May be sprinkled with nuts or coconut. Refrigerate until hard and break in pieces.
NOTE: Let chips melt a few seconds before spreading. Let butter melt some before adding the sugar. This prevents the sugar from sticking to the pan.
