Bayern,who have now won seven straight league matches,are on 64 points with Dortmund still on 57. RB Leipzig are third with 54.
"I do not live in the future. The here and now is important,"said Bayern coach Hansi Flick."We wanted to win today and take a big step forward. We did that. We were focused,decisive and courageous at times. I am satisfied with my team."
The Bundesliga restarted 10 days ago after a break of more than two months due to the COVID-19 pandemic,with games played without supporters to reduce the risk of infection.
It all started well for hosts Dortmund with teenage sensation Erling Haaland almost scoring in the opening seconds as Bayern's Jerome Boateng had to clear the ball off the line.

The visitors found their footing and had their own effort cleared off the line when Lukasz Piszczek denied Serge Gnabry from five metres.
In a fluid and entertaining first half Norway international Haaland should have done better when he was sent through in the 33rd minute with Alphonso Davies stealing the ball away.
