See how the bottoms of the cookies are darker than the tops? With a single pan, the pan heats up quickly and cooks the bottoms of the cookies faster than the tops (because metal is a better conductor of heat than air). With double-panning, this effect is lessened.
Try spacing them out farther and double-panning (cookie on parchment on pan on pan)
Why two pans? I’ve never had to do that before.

Airbake pans are the shit. Eliminates the need for double panning.
I never felt the need to double pan. Whatever that is.
If you read my parent comment, you would know perfectly well what it is.
Congratulations on your cookies never getting too hard on the bottoms, then!
