The winning variant was unveiled on the brand’s Facebook page after it saw off competition from Coconut, Hazelnut and Choc Fudge.
The bar will go on sale next month and will be supported by a nationwide advertising push.
It marks the latest phase of the brand’s £5m ‘Choose a Chunky Champion’ campaign, which is targeting 18 to 30-year old men, who spend 30 minutes a day on Facebook.
The chocolate maker claims last year’s campaign was the “biggest confectionery singles event ever for Nestlé UK & Ireland” with over 60,000 votes cast on Facebook and 11 million bars sold.
Last September, Nestlé extended the original campaign with promotions for its Chunky White Chocolate variant, the most recent permanent addition to the Chunky range, after claiming it had been the fastest selling bar during the crowdsourcing push despite not winning the vote.
