Parkin or Perkin is a gingerbread cake traditionally made with oatmeal and treacle, which originated in northern England. Often associated with Yorkshire, particularly the Leeds area, it is very widespread and popular elsewhere, notably in Lancashire. Parkin is baked to a hard cake but with resting becomes moist and even sometimes sticky. In Hull and East Yorkshire, it has a drier, more biscuit-like texture than in other areas.
