Lamingtons are a popular Australian dessert made from squares of sponge cake that are dipped in chocolate icing and rolled in desiccated coconut. They are often served as a sweet treat at parties, picnics, and special occasions. The origins of lamingtons are debated, but they are believed to have been named after Lord Lamington, a governor of Queensland in the early 1900s. Some variations include adding a layer of jam or cream between two pieces of cake, creating a delicious filled version of this classic dessert.
