The opulent eight-finger bar allows customers to choose from 1,500 flavor combinations, and also features personalized packaging.
The new “KitKat Chocolatory” creation isn’t exactly a cheap thrill, though — each bar will set you back £14 ($17).
As well as mixing and matching flavors, customers will be able to opt for British classics like Eton Mess, Cherry Bakewell and Earl Grey.
Whisky & Ginger bars are also available — as is a flavor the company doesn’t describe but calls “Jewels of the East.”
“This is the biggest news for KitKat since the introduction of the KitKat Chunky exactly 20 years ago,” Rabia Khan, Head of KitKat Chocolatory for Nestlé UK & Ireland, said in a press release.
It isn’t Nestlé’s first attempt to stay ahead of changing consumer tastes and trends.
“We know how much people enjoy experimenting with new and exciting KitKat flavours and the KitKat Chocolatory offers a whole new, premium KitKat experience as well as the chance to create your very own personalised break and have it delivered right to your door,” Khan added of the new product.
The bars will be available from John Lewis stores around the country from September 26 to Christmas Eve.
In the United States, KitKat bars are made by Hershey under license from Nestlé.
