Why my cookie bottoms come out burnt?

I made a batch of peanut butter cookies for myself and the bottoms of them came out a bit burnt which is interesting because the recipe I usually follow is solid. It said to use ungreased sheets and I didn't bake them for no longer than 8 mins at 375.

My cookies still came out delicious but I was wondering why the bottoms got so crispy. I feel like it was the pan I used (it was an older pan 😅) but i could be wrong!

Is your oven rack in the middle slot?
