Lampard, 27, hit his 50th and 51st goals of his Chelsea career, but it took a little time for the Londoners to get into their stride.
The visitors parked the proverbial bus in front of their penalty area and then went to the garage to get a second.
Such were the Midlanders' negative tactics that they did not have an attempt on target or even off target all match.
Chelsea took the lead on 23 minutes. Collecting the ball, wide on the right, Didier Drogba, checked inside and sent a low left-footer across the area. Michael Essien dummied the ball and it fell invitingly to Lampard.
He was unmarked ten yards out on the left, but pulled the ball to his favoured right foot and planted the ball between post and goalkeeper Chris Kirkland's despairing left-handed dive.
Albion were the chief architects of their downfall and Chelsea's second was typical.
Two minutes from the end of the first half, Shaun Wright-Phillips read the flight of the ball better than Paul Robinson on the by-line.
The winger stole the ball and cut it back into the gleeful path of Jose Cole.
The England midfielder struck the ball low and first time, 12 yards out and it arrowed into the unprotected net.
The second half must have seen an eternity for the visitors as Chelsea completely dominated possession and play.
Drogba could have scored on 61 minutes, but Kirkland produced a wonderful save from the Ivory Coast striker's header. Then Robinson blocked an Essien follow-up to spare their blushes.
But within seven minutes, the game was over as Chelsea netted their third.
From a deep corner the ball fell to Asier del Horno on the far post.
The Spanish defender hooked the ball back to the centre of the six-yard area and Drogba was on hard to tuck home a smart right-footer past Kirkland.
Now it was a question of not if Chelsea would win, but by how many?
Jose Mourinho rang the changes bringing on Hernan Crespo, and Arjen Robben. The Dutch winger instantly proved just why he is a vital cog in the side.
On 80 minutes, he ran Ricardo Scimeca ragged and propelled himself and the ball into the by-line position.
A little bit of luck saw the ball fall to Crespo, whose smart first-time pass went directly to Lampard.
It was a simply matter for him to plant the ball, comfortably into the near post giving Kirkland no chance to recover position.
Chelsea hit the top of the table after three matches of the new season and it will take a superhuman effort from Arsenal or Manchester United to knock them off it.
