Angelfood cake, pancake, etc.
Also, why limit pies to those baked in pie tins? Hand pies are perfectly valid, and I think there's a better argument for calling a cobbler made with a completely enclosing crust a pie than there is for calling a crumb-topped apple dessert a pie, even if it's baked in a pie tin and has a bottom crust.
Oh, and here:
Tarte Tatin a tart that's baked like a cake, turned upside down and becomes a tart.
Also, where do we draw the line? A
pasty is obviously a pie. Thus, so is an empanada. However, is a potsticker a pie? Ravioli? What about a
baozi? They're filling completely enclosing in a wrapper, but they're not made with pastry. However, a crumb crust doesn't completely enclose, and it's still counted as a pie.
Trying to categorize food is pretty damn futile.
