The German forward was in fine form for The Blues’ Carabao Cup clash at home to Championship opponents Barnsley.
Chelsea put the visitors to the sword, netting six goals on a comfortable night at Stamford Bridge.
And it was 21-year-old Havertz who stole the show with three of those to help his new club cruise into the fourth round.
Speaking after the match, Havertz said: “I’m very happy to score my first goal here at Chelsea, I’m very happy about the win and happy about my three goals and I hope we can continue like that.”
Chelsea took the lead when striker Tammy Abraham nicked in to steal a loose pass before sidefooting past the goalkeeper on 19 minutes.
Shortly after Havertz broke his Chelsea duck, largely due to the quick thinking of his strike partner.
Mason Mount fed a ball into the feet of Abraham who, noticing Havertz’s run behind him, dummied the ball between his legs to allow his teammate to control and finish to get off the mark.

It was not to be the last time the duo struck up a decent connection on the night.
Chelsea’s third though came from a different source as good pressing high up the field enabled Ross Barkley to gain possession before hitting a low driven shot into the bottom corner from the edge of the box.
Similarly tenacious work defending from the front set up Chelsea’s fourth, as Mount crossed in for Abraham, whose deft backheeled flick found Havertz to apply a calm left-foot finish into the far corner.
Just ten minutes later the pair were at it again, this time a ball into Abraham on the halfway line was turned round the corner into Havertz’s path.
What did you make of Kai Havertz’s performance? Have your say below.
As he bore down on goal he poked the ball past the onrushing keeper leaving him with the simple task of tapping the ball into the empty net for his first-ever senior hat-trick.
Discussing the performance of his new £70m signing post-match, boss Frank Lampard said: “It was a great exercise for him, another game to see how we want to work off the ball, but also have freedom on the ball and combinations with Tammy [Abraham].
“It’s the first of many great nights for him.”
Chelsea’s rout was completed seven minutes from time as left-back Ben Chilwell – making his first appearance for the club – swung a cross onto the head of Olivier Giroud to make it six.
