Confirmation of the bumper takeover also sparked fears of significant job losses at Cadbury, although Kraft – branded "a plastic cheese company" by one critic of the proposed marriage – would not be drawn on the subject.
The City Takeover Panel said yesterday that Hershey and Italian group Ferrero, who have both previously expressed their interest in Cadbury, have until Monday to clarify their intentions.
But Keith Bowman, equity analyst at Hargreaves Lansdown Stockbrokers, said: "This long battle looks to be finally drawing to a close, with price proving the determining factor. The likelihood of Hershey throwing its hat into the ring looks remote, given the required level of debt which it would have to support."
Kraft chief executive Irene Rosenfeld broke the deadlock with Cadbury's board by injecting more cash into the cash-and-shares offer, increasing the value to 840p a Cadbury share. In addition, Cadbury shareholders will get a special 10p dividend, bringing the total value of the new offer to 850p.
That compared with a previous rejected offer of 769p. Cadbury's shares closed up 29p at 836.5p yesterday.
The deal would create the world's biggest confectionery group by ending the 186-year-old independence of the British icon.
The enlarged group brings Cadbury's Dairy Milk chocolate and Trident gum, and Kraft's Milka, Toblerone and Terry's chocolate brands under one roof.
Warren Buffett, the US investment guru who owns 9.4 per cent of Kraft, had warned Rosenfeld not to overpay and issue too many new Kraft shares.
Kraft responded by saying it was issuing 265 million new shares compared with its original plan to issue 370 million.
Rosenfeld said: "We have great respect for Cadbury's brands, heritage and people. We believe they will thrive as part of Kraft Foods."
She increased Kraft's annual cost savings target to at least $675 million (412m) by year three, up from $625m, but made no mention of possible job losses at Cadbury 46,000 global workforce.
Cadbury called Kraft's previous offer "derisory", and claimed the US giant was a low profit-margin conglomerate trying to acquire the British group "on the cheap".
Yesterday's deal had its critics. Felicity Loudon, a fourth generation member of Cadbury's founding family, said: "I'm horrified. We shouldn't give up. I think there's a cultural imbalance. For a quintessentially, philanthropic iconic brand to sell out to a plastic cheese company – there's no mix there."
Stephen Boyd, assistant secretary of the Scottish TUC, said: "Observers are united in the belief that there is little industrial logic behind the bid."
Some confusion surrounded the position of one leading British shareholder in Cadbury, Edinburgh-based Standard Life Investments, which holds under 1 per cent of the shares.
David Cumming, head of UK equities at SLI, said: "We are supportive of the management's decision although the achieved price is slightly light of our stated target." Cumming had suggested on Monday that a price of above 9 a share would be necessary to secure SLI's support.
