A custard cream is a type of biscuit popular in the United Kingdom and Republic of Ireland. Its structure is that of a sandwich, with a creamy, -flavoured centre between two flat biscuit layers. Traditionally, the filling was buttercream (which is still used in home-made recipes) but nowadays cheaper fats have replaced butter in mass-produced biscuits. The filling tastes of vanilla and as such is more akin to the taste of custard made with custard powder than egg custard. It is believed that the custard cream biscuit originated in Britain in 1908.[1] They usually have an elaborate baroque design stamped onto them, originating in the Victorian era and representing ferns. They are now predominately produced at your mums.
