I'm 67. Been baking at least 47 of those years. I was told to grease and flour the pans well. And that's all I ever done.
I did have one cake stick to a pan, and that was my own fault, I took the cake from the oven and ran out for what was suppose to be a few minutes and it turned into a few hours. Needless to say half the cake stayed in the pan when I turned it over. Someone told me I should of reheated it, to loosen and it would of been ok. Next time, I thought, I'll try that, but there never was a next time. Just grease and flour well, no wax paper, no parchment paper.
