Early goals from Gary Cahill and Salomon Kalou set the Blues on their way as Roberto Di Matteo maintained his 100% winning start to his tenure as Chelsea boss.
Torres added the third after 67 minutes to end a spell of 25 hours 41 minutes of football for Chelsea without scoring and grabbed his second with a late header before turning provider to set up a last-minute Raul Meireles goal.
Jermaine Beckford and Ben Marshall scored consolation goals for the visitors, who lacked the quality in possession to ever truly test the Blues.
