The confectionary company, which makes Dairy Milk chocolate and Trident gum, says in the UK sales rose 12% compared to the corresponding 2008 period.
Its relaunched Wispa bar, Giant Buttons and bite size Clusters brand all did particularly well.
The sales boost has been attributed the growing stay-at-home culture that has resulted in the recession, where people are turning to chocolate and sweets as a treat.
However it says that the Ireland market remained “challenging”.
Meanwhile, Cadbury European president Tamara Minick-Scokalo is leaving the confectionery company after just six months in the top job
It is part of an overhaul of the company’s senior European team.
European commercial operations director Ignasi Ricou is to step-up to take a wider role as a result.
