I've seen these little outlets of heaven around the UK, but the one I tend to frequent is in the Covered Market in Oxford. The cookies in question are luscious, meaty concoctions the size of saucers, and come in a variety of flavours such as chocolate and ginger, double chock hazelnut, chocolate and orange, peanut butter and more. Because they make only small batches and business is brisk, the cookies are usually still warm when you buy them. Sin in a paper bag.
