I think of the Ülker Chocolate Wafer bar as the king of the vast variety of wafer bars. The hazelnut cream filling is substantial and warm to offset the light crisp wafer cookies. The chocolate that enrobes the center is thin and delicate but rich and creamy, as well. It really doesn't get much better than that for wafer bars. Some have more bells and whistles (see the array of Kit Kat flavors or even the new Nestle Crunch Girl Scout Cookie Candy Bars), but these simple classic Turkish treats are the best!
