Empire biscuit

An Empire biscuit is a sweet biscuit originating in Scotland and popular in the North East of England. It is also popular in Northern Ireland, as well as Canada (particularly iconic in Winnipeg and Hamilton). Empire biscuits were originally known as German biscuits but were renamed during World War I due to anti-German sentiment. Other regional names include Imperial biscuits or double biscuits. Empire biscuits are loved for their buttery texture, sweet jam filling, and the extra sweetness from the icing, making them a popular choice in bakeries and for afternoon tea.
