The basic recipe is the same as my normal Chocolate Chip Cookies I made back in May, but for these you simply have to swap the milk chocolate to white chocolate. For these I prefer using bigger chocolate chunks so I buy the bars of white cooking chocolate and chop them up using a kitchen knife. After baking for 8-10 minutes, the cookies will be fairly soft, but take them out when they go golden because they will firm up when they cool (whilst still leaving slightly soft cookie dough centres!)
