Bath bun is a traditional sweet bread roll originating from Bath. The buns are circular, with nib sugar and caraway seeds on top of their highly glazed exterior. The texture is dense and close, while the flavor is lightly spiced and sweetened, with lump sugar underneath.

The milk-based yeasted dough for Bath buns is usually based on plain brioche dough or rich egg and butter dough with caraway seeds. Although there are disputes about the origins of these buns, the ones made from a recipe dating back to 1679 are still available in the town of Bath.
