The 27-year-old winger was omitted from the original 30-man squad head coach Andy Robinson announced in late September - but he has responded with six tries in four games for Northampton.
Cohen has forced his way ahead of Gloucester winger James Simpson-Daniel and features among six changes for the Tests against Australia, New Zealand and Samoa at Twickenham.
Three of them were injury-enforced with Joe Worsley, Iain Balshaw and Alex Brown replaced by Andy Hazell, Tom Voyce and Steve Borthwick respectively.
But Simpson-Daniel, Stuart Abbott and Tom Palmer have been demoted to the stand-by list.
Olly Barkley's recent form for Bath earned him selection ahead of Abbott and Leicester lock Louis Deacon, having been called into the training squad as injury cover, retains his place ahead of Palmer.
Head coach Robinson said: "I've had to make some changes to the squad because of injuries and others are based on current form but all the players involved are there on merit.Â
"There will be some disappointed players from the first 30-man squad I announced last month but I will always stress that the door to selection is open."
Cohen has a magnificent try-scoring record for England, with 29 inÂ 46 appearances, but his last red rose cap came off the bench in the 19-13 RBS 6 Nations defeat to Ireland.
Cohen's form dropped last season as Northampton struggled to avoid relegation. He was asked to plug a gap in the centres and missed out on selection for the British & Irish Lions tour to New Zealand.
But Cohen took himself off the Lions stand-by list in order to take a complete break from the game and Robinson is delighted to see the World Cup-winner has returned stronger for it.
He scored twice in the Powergen Cup win over Worcester, again in the last minute to help Northampton beat London Irish in the Guinness Premiership and then ran in a hat-trick in the Saints' European Challenge Cup win over Viadana on Saturday.
"Ben Cohen has returned to the squad and he has been in excellent form for his club," said Robinson.
"I feel that he is returning to the form that made him such an important member of the squad two years ago and I'm looking forward to working with him again."
Worsley's injury had led to speculation Lawrence Dallaglio could earn an swift recall into the England back row.
But Robinson dismissed the possibility of either Dallaglio (broken ankle) or Jonny Wilkinson (appendix) being rushed back to Test rugby too soon.
He wants both players to work their way back to full match fitness with Wasps and Newcastle respectively before they will be considered for England.
Robinson will announce his team to play AustraliaÂ on November 6. England face the Wallabies at Twickenham on November 12 before tacklingÂ the All Blacks (Nov 19) and Samoa (Nov 26) on consecutive weekends.
