A Cadbury Creme Egg is a chocolate product manufactured in the shape of an egg. The product consists of a thick milk chocolate shell, housing a white and yellow fondant filling which mimics the albumen and yolk of a real egg. Creme Eggs are the best-selling confectionery item between New Year’s Day and Easter in the UK, with annual sales in excess of 200 million and a brand value of approximately £50 million.
Creme Eggs are produced by Cadbury UK in the United Kingdom and by Cadbury Adams in Canada. They are sold by Kraft Foods in all markets except the USA, where theHershey Company has the local marketing rights. At the Bournville factory in Birmingham, in the UK, they are manufactured at a rate of 1.5 million per day. The Creme Egg was also previously manufactured in New Zealand but is now imported into that country from the UK.
While filled eggs were first manufactured by the Cadbury Brothers in 1923, the Creme Egg in its current form was not introduced until 1963. Initially sold as Fry’s Creme Eggs (incorporating the Fry’s brand), they were renamed “Cadbury’s Creme Eggs” in 1971.
