The design features a new font, logo, and Glass and a Half icon, well as a new pack design based on the original Dairy Milk packaging.
The design will be rolled out across Cadbury’s single chocolate blocks from this month, before being rolled out across the rest of the range during the year.
Pippa Rodgers, brand manager for Cadbury Dairy Milk, said: “Cadbury wanted to celebrate to the brand’s roots by honouring the philanthropic spirit of its founder, John Cadbury.
“The new identity is grounded in the original intent behind the brand, linking where Cadbury came from with what it means to shoppers today – a truly authentic brand and great tasting, quality chocolate.”
