@Scrbblchick -- And I'll add that nothing should be baked in your good cake pans *but* cake or brownies. I threatened my husband with bodily harm if he made toast or pork chops or the like in my good pans! A good cake pan is worth a higher price!
Even if you have nonstick round pans, go ahead and line the bottoms with parchment paper and then butter the paper. It's a 10-cent insurance policy that will absolutely keep your layers from sticking. I never make a layer cake without doing this, and I've never had it not work. The layers come out beautifully every time.
