A KitKat made with naturally pink chocolate is to launch in the UK next week.
UK consumers will be the first in Europe to be able to buy Nestle's four-finger KitKat made with ruby chocolate from specially selected cocoa beans.
Ruby chocolate was created by Swiss company Barry Callebaut, which spent more than a decade unlocking the bean's colours and flavours.
The flavour has been described by the company as "a tension between berry-fruitiness and luscious smoothness".
It said no colours or flavours are added to create the pink hue, which instead comes from a powder extracted during the processing.
The beans are grown in the Ivory Coast, Ecuador and Brazil.
Pablo Perversi, chief innovation, quality and sustainability officer at Barry Callebaut, said: "I am very pleased to see the result of our partnership with Nestle, the iconic four-finger KitKat made with our Ruby chocolate.
"Consumers across the world will be intrigued by the unique taste of this crispy delight."
The new KitKat was first introduced earlier this year in Japan and Korea.
Alex Gonnella, marketing director for Nestle's UK confectionery business, said: "Ruby chocolate is a big innovation in confectionery and we are very proud that KitKat is the first major brand in the UK to feature this exciting new chocolate."
The KitKat will be available exclusively at Tesco from April 16 with a recommended retail price of 85p.
