Twirls substituted in some Heroes chocolate boxes

Cadbury's has removed small Twirls from some Heroes chocolate boxes due to disruption in its supply chain, the confectionery giant has said.

Some tubs will now come with two full-sized Twirl bars, rather than the usual miniature ones.

It's not the first change to be made to chocolate variety boxes recently.

Earlier this month Mars Wrigley said it was removing Bounty bars from some Celebrations tubs because 40% of people hated the coconut-flavoured treat.

A spokesperson for Mondelez, which owns Cadbury's, said: "We're facing the same challenges that many other food companies have reported in recent months," citing supply chain disruptions.

"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 across a small percentage of tubs produced," the spokesperson added.

One confused user, @Andy92rew, wrote on Twitter: "Excuse me. Why is there a normal size Twirl in my box of Heroes!?"

"Twirl clearly has escaped from other friends," tweeted @SazSazzle when she found her full sized bars in the chocolate tub.

"Rest assured consumers can enjoy the same amount of chocolate as before with the overall weight of the product remaining the same," the spokesperson from Mondelez confirmed, after people began noticing the substitution.

The company also had problems supplying its Mikado chocolate sticks in September.
