Inzaghi struck after a Kaka pass on 21 minutes but Boca equalised a minute later through Rodrigo Palacio's header.
Alessandro Nesta's volley, Kaka's solo run and finish and Inzaghi's second - all in the space of 10 minutes - settled the match in Milan's favour.
Kakha Kaladze saw red, as did Boca's Pablo Ledesma, while Milan's Massimo Ambrosini scored an own goal.
"I'm really satisfied - this trophy is what I've missed all along," said Kaka.
"I really thank God for this year as we won the trophy that is so hard to get."
