Palmer scored a superb solo goal, a tap in, a goal from near the half-way line, and then a late penalty.
It all happened so fast in the first 30 minutes," Palmer told club media.
We started well and to score a hat-trick, I'm buzzing. I think the team needed that after last Sunday and some previous games. We did well tonight. It was a great game for the team and me.
We needed to come out and show something and I think from the first minute we showed what we could do. It was a good performance tonight. We're really happy with the win.
To make the decision to come to Chelsea was a big one for me and my family, but I just wanted to play football. I'm thankful to Chelsea for the opportunity and I'm buzzing."
I think my first one was my favorite," he added.
My right-footed goal was a bit of a swinger, but my first one was probably my favorite. As an attacker, you always want to help the team with goals and assists, but my main focus was playing well and trying to get into the positions to score goals."
This season has been a bit inconsistent for us," Palmer said.
We have had some poor performances, but then again we have battled with the big sides, done well and got some good wins. We need to take each game as it comes and see where we finish."
He then finished with praise for teammate Alfie Gilchrist: Everyone was buzzing for him.
Obviously, he has been at Chelsea for his whole life. He has trained with us and put 100 per cent in every day."
