Gur cake is a pastry confection traditionally associated with Dublin, Ireland. Known as chester cake in other areas, and gudge or donkey's gudge in Cork, it is similar to what is termed flies graveyard in parts of the UK, and consists of a thick layer of filling between two thin layers of pastry. The filling is a dark brown paste, containing a mixture of cake/bread crumbs, dried fruits (sultana raisins etc.), and a sweetener/binder. It has traditionally been a cheap confection, made from bakery leftovers. In bakeries, it is typically sold cut into squares of about 8 cm by 3 cm thick.
