Dortmund were without superstar striker Erling Haaland due to injury when they took on Arminia Bielefeld, but didn't miss the goal-scoring sensation thanks in part to Bellingham.
The 18-year-old helped BVB to a 1-0 lead when he was taken down for an Emre Can penalty with half an hour played, and he later put the game to bed with an extraordinary effort.
Receiving the ball on the edge of the box from captain Marco Reus, Bellingham faked to curl a shot inside the far right post, before darting past a startled Bielefeld defender.
The Three Lions regular then took on two more players, before dinking the goalkeeper and putting the game to bed.
It was a game high on quality with Mats Hummels' earlier goal rivaling Bellingham's effort as he blasted a first time volley in from the edge of the box to give his side a 2-0 lead.
Bielefeld scored a late consolation from the spot, but were unable to stop Dortmund from keeping pace with Bundesliga leaders Bayern Munich.
Dortmund trail Bayern by just a single point despite the reigning champions dismantling Hoffenheim and Bayer Leverkusen in their past two league games.
It hasn't been all good news for Dortmund though, who were utterly humiliated in the Champions League last time out as they were played off the park by Ajax during a 4-0 defeat.
Manager Marco Rose was also dealt a blow when it emerged that Haaland will be out for a few weeks with a hip flexor injury, despite only recently returning from a previous setback.
