Note to self:
Self, do not attempt to make Angel Food cake in any pan other than what is specified. Never fill it to the top of the pan. Angel Food expands. A LOT.
Oh YES self, it would have been darn cool to make a castle shaped angel food cake, but it really is impossible to get out. A dessert as light and airy as this is not meant to be violently ripped from the pan in pieces by voracious visitors and crammed in their mouths.
