The game witnessed the fastest FA Cup final goal when Louis Saha broke the deadlock after 25 seconds.
Goals from Didier Drogba and Frank Lampard in each half ensured that the trophy went to Stamford Bridge in Guus Hiddink's last game as the Blues' manager.
Alongside his job as Russia coach, the Dutch tactician took over Chelsea on permanent bases in January.
Fiery Start
Saha did well to put Everton ahead, when he latched onto Marouane Fellani's header with a left-footed volley that was too surprising for Petr Cech to deal with.
However, Chelsea equalised on 21 minutes after a neat move led to Drogba beating Joleon Lescott to head Ashley Cole's cross past Tim Howard.
Cole could have turned from provider to scorer one minute before the interval, but the English international shot wide and high from close range.
Chelsea looked much better in the second half, and another Lampard pass released Nicolas Anelka through.
The Frenchman's lob went high under pressure from the Everton defence.
Everton's only appearance of the second-half came through Saha, whose header from Leighton Baines cross went wide off Cech's bar in the 67th minute.
Lampard scored the winner for his team five minutes later. The former West Ham man did well to keep possession before firing with his left from outside the box past Howard.
Hiddink's men thought they scored a third twelve minutes from time. Florent Malouda's long-range shot went in off the bar and out but the linesman didn’t call for a goal.
