Ideally, on SW, you will be trying to avoid giving in to cravings like this by re-educating your taste buds; however, this is easier said than done! If I were you, I would be inclined to buy something like a pack of Mr Kiplings double choc chip cake bars, have one and count the Syns as sometimes this is more satisfying than an imitation 'cake'. You could, perhaps, freeze the remaining bars so that you're not tempted to have more than one.
