The brand also recently released small race-car-shaped chocolate bars, signed off as ‘Official Chocolate Bar of Formula 1’.
Stephanie Scales, Marketing Manager for KitKat, Nestlé UK & Ireland, said: “Formula 1 brings unmatched energy and global cultural relevance, and we wanted to translate that into something that KitKat fans and Formula 1 lovers could enjoy.
“With its striking marbled effect and smooth caramel flavour, it’s poised to capture attention and generate real excitement for shoppers.”
The bar is also part of an on-pack promotion, allowing shoppers to win F1 prizes until April.
These include a full expenses paid trip to the Grand Prix in Monaco or Britain.
In the UK, KitKat is an absolute staple. The “Have a break” tagline has been used since the 1950s, successfully positioning the product as a staple for breaks.
It is bought by more than 60% of households annually and is considered the most global chocolate brand, with massive, consistent production (over 4 million bars a week in York alone).
The bars are being sold individually and in multi-packs, and are available across UK stores now.
