Daniel Sturridge headed the visitors in front in the second minute, teed up Lampard in the 15th and Chelsea then raced into a 4-0 lead, two errors in quick succession by home goalkeeper Adam Bogdan allowing the Blues pair another goal each. Dedryck Boyata pulled one back for Bolton a minute into the second half, but it counted for little as Lampard completed his treble just before the hour mark.
Lampard believes the side are progressing well with Portuguese manager Andre Villas-Boas at the helm, saying: ""I think there have been a lot of signs of our developing understanding in recent games but Bolton was the day where we put it together as the finished article."
He added: "We are trying to show what we are about in training and when a new manager comes in, sometimes it can take time for his effect on the training ground to carry over onto the pitch.
"There were a lot of times when we had some okay performances early in the season - Manchester United, Valencia, for example - and we have played a lot of games where we have created a lot of chances and not finished them off, which takes the gloss off a result sometimes.
"Everything happened for us from the start. You saw the brand of football that we played - the passing and movement and quality throughout the team - and that is what we are working towards.
"We moved the ball and passed the ball and passed the team to death. On top of that, we have created a lot of chances and taken them. We need to keep doing that."
The victory was Chelsea's fifth in seven Barclays Premier League games this season and saw them back up to third in the table, three points away from pacesetters Manchester United and Manchester City.
