Treacle tart is a traditional British dessert. The earliest known recipe for the dessert is from English author Mary Jewry in her cookbooks from the late 19th century.^[1]

It is prepared using shortcrust pastry, with a thick filling made of golden syrup (also known as light treacle), breadcrumbs, and lemon juice or zest. The tart is normally served hot or warm with a scoop of clotted cream, ordinary cream, ice cream, or custard. Some modern recipes add cream, eggs, or both in order to create a softer filling.

Treacle bread^[2] is a homemade bread popular in Ireland and is similar to soda bread but with the addition of treacle.
