Did I just ruin my new cake pans?
OK, I'm not much of a baker and I made choco chip cookie bars for the first time using brand new half cake pans. Here's where I think I messed up...I cut the bars with a kitchen knife while they were in the pan. Now I have two cake pans that are heavily scored...I can feel little ridges. Did I just ruin my cake pans? What should I have done?
