The champions surged to the top of the league courtesy of a sensational performance by Lewandowski who came on at the start of the second-half.
He scored five goals in nine minutes as the Bavarians came from behind to trounce Wolfsburg 5-1.
Trailing at the pause to Daniel Caligiuri's strike for the visitors, Bayern coach Pep Guardiola sent on the Poland international for Thiago Alcantara. The move paid dividends within six minutes of his introduction as he equalised with a strike from close range. That was after 51 minutes.
The second, a minute later, was a shot from outside the penalty area and the 27-year-old saved the best for last.
On a counter-attack, Thomas Muller fed Mario Gotze on the right wing and Lewandowski met his cross with a scissors kick at the edge of the box. The Wolfsburg goalkeeper Diego Benaglio stood motionless as the ball rifled into the top right hand corner. Sixty-one minutes of the game had passed.
It was the fastest five goals scored by one player in Bundesliga history.
Social media was chirping in response on Wendesday. Bayern Munich defender Jerome Boateng took to the dictionary to hail his striker. "Naprawde? Gratulacja! (Really? Congratulations!) I've learnt Polish after that performance," he said.
Lewandowski's former Borussia Dortmund team-mate Mat Hummels, who also played in the 4-1 Champions League semi-final win over Real Madrid in April 2013 when the striker scored four goals, was just as incredulous.
"Hahahhahahahah - I've never seen anything like that in my life," tweeted Hummels.
The former England striker and TV pundit Gary Lineker wrote "Utterly ridiculous!", next to a picture of the Bayern-Wolfsburg scoresheet and ex-Norway international Jan Aage Fjortoft, who played in the Bundesliga, tweeted: "That's a miracle."
Dortmund can draw level with Bayern on Wednesday night. They travel to Hoffenheim and will regain the lead of the Bundesliga provided they beat their hosts by three goals.
