Having also scored in the 2-1 FA Cup final victory over Liverpool a fortnight ago, Drogba flirted with the villain's role four minutes into extra time on Saturday as his foul on Franck Ribery saw Bayern awarded a penalty.
But Bayern's ex-Chelsea wing Arjen Robben could only weakly hit to Petr Cech's right and his shot was quickly gathered.
Drogba worked tirelessly throughout, often back-tracking to help out in defence and grew in stature as the game wore on before keeping his cool to nail the final penalty past Munich's Manuel Neuer.
Having joined the Blues from Marseille in 2004, the Ivory Coast forward has said he will sit down with Chelsea's bosses to discuss a new deal once the season is over.
It was the towering striker who helped put the Blues in Saturday's final with the first-leg winner at Stamford Bridge against Barcelona in the last four.
If the former African Player of the Year has played his last game for the Blues, the possibility of Drogba available as a free agent is likely to arouse interest across Europe, but he has denied reports linking him to Barcelona.
Having been sent off four years ago, Drogba made good on his pre-match promise to make amends for his Moscow misery by ending Chelsea's long wait to be crowned kings of Europe.
With Drogba unable to take a penalty in that final's shoot-out, the Ivory Coast striker had to watch from the sidelines as John Terry and Nicolas Anelka's spot-kick misses gifted the trophy to United.
"In Moscow it was very difficult," said Drogba.
"It was very painful for the players, for the club, for the fans, and today we managed to change it and again it was an amazing game, a crazy game."
