The Chelsea Bun is a classic British sweet bun: a light, yeasted dough rolled out flat, spread with butter, brown sugar, and currants (and sometimes cinnamon or mixed spice), then rolled into a log and sliced into rounds. The rounds are baked together in a square tin so they stick together, creating the characteristic square shape. They are finished with a sticky sugar glaze that makes them irresistibly glossy and sweet. A Chelsea Bun is the sophisticated older cousin of the cinnamon roll.

About Chelsea Bun

Chelsea Buns originated at the Bun House in Chelsea, London, in the early 18th century. The Bun House, run by Richard Hand (known as 'Captain Bun'), became so popular that it attracted crowds including King George II and George III, who were said to be fans. The shop closed in 1839 but the bun's recipe lived on and became a staple of British bakeries. Today, Chelsea Buns are sold in bakeries, supermarkets, and coffee shops across Britain, representing one of the country's oldest and most beloved baked goods.

Cooking Tips

Let the dough prove fully — it should be noticeably puffier before rolling.
Spread butter generously to the very edges so the filling spirals to the outside.
Pack the buns snugly in the tin so they support each other as they rise.
Glaze immediately from the oven with warmed golden syrup for maximum shine.
