The first chocolate eggs appeared in France and Germany in the 19th Century, but they were bitter and hard.
As chocolate-making techniques improved, hollow eggs like the ones we have today were developed.
They very quickly became popular and remain a favorite tradition with chocolate-lovers today.

The chocolate Easter egg
The chocolate Easter egg has developed from the simple type wrapped in paper to the beribboned variety wrapped in brightest foil and packed in a box or basket.
The first chocolate Easter eggs were made in Europe in the early 19th Century with France and Germany taking the lead in this new artistic confectionery. A type of eating chocolate had been invented a few years earlier but it could not be successfully moulded. Some early eggs were solid while the production of the first hollow chocolate eggs must have been rather painstaking as the moulds were lined with paste chocolate one at a time!
John Cadbury made his first ‘French eating Chocolate’ in 1842 but it was not until 1875 that the first Cadbury Easter Eggs were made. This may have been because he was not sufficiently impressed with continental eggs to wish to compete with them or because he was too busy with other aspects of his growing business. In fact, progress in the chocolate Easter egg market was very slow until a method was found of making the chocolate flow into the moulds.
The modern chocolate Easter egg with its smoothness, shape and flavour owes its progression to the two greatest developments in the history of chocolate – the invention of a press for separating cocoa butter from the cocoa bean by the Dutch inventor Van Houten in 1828 and the introduction of a pure cocoa by Cadbury Brothers in 1866. The Cadbury process made large quantities of cocoa butter available and this was the secret of making moulded chocolate or indeed, any fine eating chocolate.
The earliest Cadbury chocolate eggs were made of ‘dark’ chocolate with a plain smooth surface and were filled with dragees. The earliest ‘decorated eggs’ were plain shells enhanced by chocolate piping and marzipan flowers.
Decorative skill and variety soon followed and by 1893 there were no less than 19 different lines on the Cadbury Brothers Easter list in the UK. Richard Cadbury’s artistic skill undoubtedly played an important part in the development of the Easter range. Many of his designs were based on French, Dutch and German originals adapted to Victorian tastes. From Germany came the ‘crocodile’ finish which by breaking up the smooth surface, disguised minor imperfections; still used today by some manufacturers, this was the forerunner to the many distinctive finishes now available.
