The artists - more than 4,000 employees at the west London office park plus members of the local community- broke the Guinness World Record with their edible depiction of attractions including the London Eye, Big Ben, the Royal Albert Hall and Wembley Stadium.
The new official holder of the record for largest candy mosaic measures 40 square metres (48 square yards). It beats the previous record of 37.126 square metres achieved by the Calderdale Education Service in Halifax on February 4-5 2006.
Frank Chambers, adjudicator for Guinness World Records, said: "The mosaic is really fabulous. You can see the Smarties' colours all the way through the park."
The mosaic was designed to promote London to visitors. It will be moved to an office building in the park until early August to prevent the chocolate melting and birds feasting on it.
