A stunning Frank Lampard strike ended Everton's resistance and ensured Chelsea's interim boss Guus Hiddink brought the curtain down on his brief spell in English football by collecting the FA Cup.
The Toffees had made a dream start when Louis Saha put them ahead after just 25 seconds - the quickest goal in Cup final history.
But Chelsea came back strongly and equalised through Didier Drogba's header before Lampard fired home the winner from 25 yards with 18 minutes left.
The margin of victory should have been greater as TV replays showed that Florent Malouda's spectacular strike moments later had crossed the line after bouncing down off the bar, but referee Howard Webb did not give the goal.
In the end it made no difference to Chelsea, or Hiddink, who deservedly has a trophy to show for the impressive work he has done at Stamford Bridge as he returns to his job with Russia.
Victory at a sweltering Wembley brings to an end the Dutchman's brief love affair with the Blues, which began when he watched from the stands as they beat Watford in the fifth round on Valentine's Day.
And his side again demonstrated the patience and power he has instilled them as they fought back to overhaul a dogged Everton side that took the lead with a terrific early strike.
