The Primrose Bakery was co-founded in the kitchens of Martha Swift and Lisa Thomas in 2004. In the last decade the bakery has gone from strength to strength, with the opening of two shops in Primrose Hill (2006) and Covent Garden (2008) and the publication of three recipe collections, Cupcakes From the Primrose Bakery, The Primrose Bakery Book and Primrose Bakery Celebrations. In October 2014 the bakery celebrated its 10th anniversary and the publication of a fourth cookery book, Primrose Bakery Christmas.
Martha Swift is now sole owner of the bakery and lives in Primrose Hill, north London, with her two daughters.
