Sky News and Reuters cite "people familiar with the matter" as saying Mondelēz has made a £200m ($263m) bid.
Mondelēz's spokesperson said, "as a matter of practice, we don't comment on market rumors or speculation." ConfectioneryNews is reaching out to the parties concerned and hopes to follow developments closely.
Mondelēz bought the Cadbury brand for about $19bn in 2010. But Burton's Biscuits holds licenses for Cadbury biscuits that predate the Mondelēz acquisition such as the right to produce, sell and market Cadbury Fingers, which it has held since 1986.
Burton’s recently brought Cadbury’s Mini Fingers and Wispa biscuits to the US market at the Sweets and Snacks Expo in Chicago this year and has earmarked the US as a priority market for the brand.
Mondelēz’s reported move for Cadbury Biscuits comes nearly a month after its $23bn takeover of Hershey failed. Analysts said Mondelēz was aiming to shore up its US presence through Hershey, but its approach was rejected by the Kisses owner.
Sky News' sources claim the Burton's negotiations are still early-staged, and may not result in a deal.
