Parkin or perkin is a sticky cake originating from Northern England, although it is mostly associated with Yorkshire. It consists of flour, oatmeal, black treacle, and either lard or butter. Many cooks like to spice it up with a hefty dose of ginger in order to elevate the flavors.

Parkin is characterized by its hard texture after baking, but if it is left in a sealed container, it becomes soft and moist. Parkin is always prepared for Bonfire Night (Guy Fawkes Night)—celebrated on November 5—but it is also commonly enjoyed throughout winter.
