The new Cadbury Dairy Milk Choca-latte hits shelves following a competition run by Mondelez which let consumers submit their ideas for a new flavour.
Cadbury Choca-latte was one of three finalists, but secured its permanent status after winning a public vote.
The new flavour was invented by 17-year-old Callum Clogher, from Ireland.
Claudia Miceli, senior brand manager at Cadbury said: “We are very excited to reveal Callum as the winner of our first ever Cadbury Inventor competition.
“His creation was both innovative and delicious and is set to be a real hit for retailers and their shoppers.”
Mondelez has now relaunched its Inventor competition to find a new flavour for 2020.
