The 27-year-old Austrian-born Kenyan was then yellow-carded in the 58th minute after a poor challenge on David Alaba, and his yellow card was among the four issued by referee Harm Osmers.
Keeper Manuel Neuer was at fault for the opener, but also produced some big saves to keep Bayern in touch with their impressive hosts, who have been the most-improved team in the league in the second half of the season.
Burkardt stunned Bayern in the third minute when he was left unattended on the edge of the penalty area and fired a thumping shot that Neuer could only help into the left corner and they doubled their lead in the 37th minute when Quaison headed past Neuer after Mwene s free-kick from the left proved a perfect, teasing delivery.
