Christmas chocolate box fans are opening their tubs of Cadbury Heroes to find there are no mini Twirl bites inside. Cadbury announced in September that the bites in the box would have to be replaced because of a shortage.
Instead, Cadbury is putting two standard-size single bars in the tub, reports The Sun.
Shoppers have taken to social media to ask why the replacement has been made.
One wrote: "Opening my box of Heroes to find two Twirls in there instead of the mini ones, does this mean I’ve won something or was there just a shortage at the factory on the mini ones?"
Mondelez, which owns Cadbury, told The Sun: "To ensure we can continue to bring our loyal consumers the products they know and love, we have temporarily substituted bitesize Cadbury Twirl in Heroes Tubs, to the slightly larger Cadbury Twirl 21g.
"Rest assured consumers can enjoy the same amount of chocolate as before with the overall weight of the product remaining the same.”
They said the problem was down to a supply chain issue.
In May this year Cadbury launched a new flavour of Twirl - with caramel. Twirl Bites are still available in pouches in most shops.
