The French superstar netted the game's opener, before brilliantly assisting Lionel Messi's first goal that levelled the scores at 2-2.
Mbappe then cleverly won PSG a penalty in the 74th-minute, which Messi converted courtesy of a delicious Panenka.
The only downside to Mbappe's virtuoso display at the Parc des Princes was the fact that he failed to score from the spot himself in stoppage-time.
Messi rejected the chance to grab a first PSG hat-trick, but his teammate couldn't take advantage of the generous act and instead fired the ball over the crossbar.
That wasn't the only time Mbappe was left feeling a tad embarrassed in Paris on Tuesday night either...
Just before kick-off, the 22-year-old was given an almighty fright in the tunnel by the referee blowing his whistle.
Mbappe's terrified reaction was priceless and the way he tried to style it out was pretty comical too.

Marco Verratti was also caught out by the referee's decision to blow his whistle as loudly as possible, but Messi and Achraf Hakimi both kept their cool.
After the match, Mbappe spoke about the penalty taking decisions made by him and Messi during the latter stages of the game.
"It’s normal, it’s respect," the Frenchman said. "He’s the best player in the world, it’s a privilege he plays with us, I’ve always said it. There’s a penalty, he takes it, period. For the second, he said, 'Take it'."
The chemistry that appears to be developing between Mbappe and Messi is certainly a huge positive for PSG - despite the team's sub-par performances overall.
If Mauricio Pochettino can sort his midfield and defence out to help the duo thrive as much as possible, the French side will be the formidable unit many tipped them to be after their summer of lavish spending.
