Bayern, who could secure their sixth consecutive Bundesliga title at the weekend, went 2-0 up seconds after the second-half restart when Gokhan Gonul volleyed a Rafinha cross into his own net.
They did manage to pull a goal back through Vagner Love's effort in the 58th minute which breathed some brief life into the hosts but Bayern substitute Sandro Wagner chested in a David Alaba cross with six minutes remaining to make sure of Bayern's victory.
"Even though the first match was 5-0, it was not easy. It is normal for the team to relax from time to time and now show the desired performance, but we scored eight goals in two games of the round of 16 and this shows how good a team we are," Bayern boss Jupp Heynckes said via a translator.
Heynckes, who said he had no preference for his side's next opponents, is now targeting a treble with Bayern on course to wrap up the Bundesliga title having also reached the German Cup semi-finals.
"Of course we are hungry [to complete a treble]. We want the Champions League, we are very determined, and we also want the German Cup."
Barcelona and Bayern will join Real Madrid, Juventus, Liverpool, Manchester City, Roma and Sevilla in Friday's quarter-final draw.
