The England captain needed the help of a deflection, but still made no mistake at all from Alphonso Davies' assist.
The goal came either side of efforts from Leroy Sane and a late wonder-strike from Mathys Tel, earning Bayern a 4-0 win in the first Bundesliga match of the season.
After being kept off the scoresheet in a debut 3-0 defeat to Leipzig in the German Super Cup, Kane was eager to get off the mark.
And it looked like it might not come, with five shots throughout the match, Bremen captain Marco Friedl was man-marking the former Tottenham man with plenty of force.
However, Kane found himself alone in the 74rd minute, and after demeaning the ball from Davies, received it and tucked home in usual fashion.

It wasn't all good news though, with Kane collapsing to the floor eight minutes later while all alone, but he later came back on after treatment from club medics.
Shortly after, he was then replaced by Eric Maxim Choupo-Moting, in what appeared to be a precautionary move from Tuchel.
The goal proved to be crucial, with Bremen looking the better side in the second half, and star striker Niclas Fullkrug giving the Bayern defence a torrid time.
