Chocoholics have been left absolutely baffled by trying to figure out Cadburys' Mystery Bars in order to win a massive prize.
The two limited-edition bars each contain a secret flavored filling, with flavour detectives in with the chance of winning a €5,000 mystery prize.
The bars are available in the majority of retailers at the moment, but will be gone once October 7 hits, with Cadbury expected to reveal the new tastes shortly afterwards.
