A retro Cadbury chocolate bar is returning to supermarket shelves after a two decade absence.

Top Deck is being relaunched in the UK as part of the confectioner’s 200th birthday celebrations.

First launched in 1993 the sweet treat is made up of two separate layers of milk and white chocolate.

And in a real trip down memory lane for fans of the original chocolate - the bar is also being returned to supermarket shelves in its original packaging.

A spokesman for manufacturer Mondelēz International, which owns Cadbury, added: “We’re delighted to be answering Cadbury fans’ requests and relaunching Cadbury Top Deck in the UK for a limited time, as part of our 200-year anniversary celebrations.

“With two delicious layers of milk and creamy white chocolate, every bite of Cadbury Top Deck will reward you with pure indulgence.”

It was on March 5, 1824 that John Cadbury opened his first grocery shop – with his family going on to become the world’s largest chocolatiers.

The Top Deck bar is not the first Cadbury product to have returned to shelves in the last year.

At Christmas Dairy Milk chocolate coins - in a netted bag - were brought back into production after social media appeals from fans in the UK.
