The new bar features a combination of crispy wafer with a salted caramel flavoured topping, which is then covered in milk chocolate.
Nestlé has also given the bar a ‘retro’ sweet shop packaging design featuring turquoise stripes, which aims to evoke the “childhood memories” of consumers.
This release comes as part of Nestlé’s flavour rotation strategy, as the company adds a new flavour to its KitKat range each year in order to provide new experiences for consumers.
According to Nestlé, last year’s New York Cheesecake flavour proved a hit with millennial consumers, with 70% saying they would try the bar again.
Natasha Lawless brand manager for KitKat said: “KitKat fans love exciting new combinations and flavours from their favourite brand, and with the ongoing popularity of salted caramel, we thought it was only right to bring this salty-sweet combination to KitKat Chunky.
“Following the incredible success of KitKat Chunky New York Cheesecake and KitKat Chunky Cookie Dough, this year’s bar has all the credentials to be yet another smash hit.”
KitKat Salted Caramel Fudge bars will be available from selected Sainsbury’s stores from 15 August, and from all major UK retailers from 20 August.
Earlier this year, KitKat became the first brand to release a ruby chocolate product in the UK with the release of KitKat Ruby in April.
