I have this baking dish ordered because of the positive reviews and because I thought I could do that! Unfortunately, I have to confess that not my first attempt so great was ... Today, I know, the dough was laid on! It was visually rather a marble cake than a chessboard! But we must not give up !! So, the second attempt: This time I had a little more liquid dough than before and I have (unfortunately in English) looked at even before appropriate videos on Youtube! Lo and behold, I had a perfect checkerboard! Since then I have the form, which, incidentally, has a perfect non-stick coating (was my first form of Wilton but certainly not my last !!) already used more often and always when the cake is cut, the guests are delighted! I can only recommend the form! By the way you can find at Chef doctor ordered it! I hope I could help a bit!
