The limited-edition packaging will be available from early May across Cadbury Roses 423g tins and Cadbury Dairy Milk 360g tablets.
The Roses tin will be emblazoned with a crown image, while the Dairy Milk design will showcase the Platinum Jubilee’s official emblem.
Benazir Barlet-Batada & David Clements, senior marketing directors at Cadbury, said: “Cadbury has a long-standing history of helping the nation come together and celebrate Royal occasions and we’ve proudly held a Royal Warrant for over 167 years.
“The new limited-edition packaging across formats will be a great way to generate excitement in store and gives shoppers a keep-sake to remember this great event.
“We’ll be giving retailers significant in-store support and would advise them to ensure the limited-edition packaging is highly visible in-store to make the most out of the occasion.”
