Twirl was invented in Dublin by Cadbury Ireland, and launched there in 1985 as a single-finger bar.

Cadbury also produce a snack sized version called Twirl Bites, which come in a bag containing several smaller Twirl-like chocolates.

In late 2019, Cadbury launched an orange flavoured variety of Twirl in the UK.

Many stores struggled to keep stock of the bar, repeatedly selling out due to the high demand.

Consumers could join a pre-sale on Twitter to get access to the first new bars,[4] while stores began to stock them in September.
