Answer 1

It’s because of the speed at which heat moves through the whole cookie.

If you double the heat outside, you do not double the speed at which the heat moves through the cookie.

Also at certain temperatures you get chemical reactions on the outside that actually slow the speed at which heat moves through the cookie, so the recommended temperature to bake a cookie is often the optimum in regards to many factors.
