Query: I've never burned cookies in my life!

These pans are terrible!!! I've been baking for 30 years, never burned a cookie in that entire time. I just bought these pans for my holiday baking and they are ridiculous! Cookies are burned on the bottoms, tops are light-colored so you couldn't even tell. The pans are now scorched and no amount of scrubbing will remove the discoloration. The only thing I didn't try was a scouring pad because that would remove the non-stick surface. Very disappointed and my whole first batch is ruined. I'm afraid to bake anything else on these now, guess I'll go back to my old pans. :((
