A Bath bun is a British sweet bun associated with Bath and made with enriched dough, sugar, and currants.
Bath buns are made from a yeast-raised dough enriched with ingredients such as butter, milk, and sugar. Traditional versions may contain currants and are often topped with sugar or crushed sugar crystals. They are softer and more bread-like than Eccles cakes, which are flaky pastries filled with spiced fruit.
The bun is connected with Bath’s eighteenth-century spa culture. William Oliver, a physician associated with the city, is often linked with its development, although the exact history of the modern bun includes several variations. Bath buns should also be distinguished from Bath Oliver biscuits, a separate hard, unsweetened biscuit originally created for spa visitors.
