All Cadbury chocolate bars sold in multipacks will shrink by the end of 2021 to reduce their calorie count, owner Mondelez has announced.
Popular treats including Crunchie, Twirl and Wispa bars will contain no more than 200 calories each when sold in a four-pack.
However, the price will stay the same. Bars sold individually will not change.
Chocolate fans took to Twitter to denounce the latest example of what has become known as “shrinkflation”.
That is when food manufacturers reduce the weight of their products without shrinking the price.
“We must play our part in tackling obesity and are committed to doing so without compromising on consumer choice,” said Louise Stigant, UK managing director at Mondelēz International.
When asked why “single-serve” bars were unaffected, a spokesperson for Mondelez said the firm believed in “offering consumers different portion sizes for different occasions”.
The spokesperson confirmed that the list price for multipacks would not change and said pricing was up to retailers.
‘Profit or health?’
Consumers were sceptical, with one tweeting that Cadbury should change the name of its Double Decker bar to Minibus.
“Cadbury trying to say that the change is for health reasons when it seems painfully obvious it’s for profit margins,” said another disgruntled customer.
This is not the first time that Mondelez has run into opposition after altering the size of its chocolate bars.
In 2016, it reduced the weight of its Toblerone bar from 200g to 150g by spacing out its distinctive triangular chunks, but it reversed the change two years later.
