Cadbury's Creme Egg moulds move down the production line at the Cadbury Plc factory in Birmingham, U.K.
Cradled in a shell of milk chocolate, the Cadbury Crème Egg filling is actually a mix of white and yellow fondant — simply sugar and water beaten into a crème. Since the first egg was made in the 1920s, new varieties include fillings of caramel, chocolate and mint.
