I have baked an angel food in a 9X13 pan but the result wasn't very satisfactory. Church ladies were doing it, didn't know about parchment paper then. This looks scrumptious, and no way did those slices come out of a tube pan. I have this double loaf pan with feet; it's for angel food cakes and big loaves of bread, got it when I lost my mom years ago, never used it. Well, Wilton still has them. Not terribly expensive. I read where you have to line that pan (16 in long) to the max with parchment paper to bake an angel food in it but that's what I would do, finally get a chance to use it for something. Then my problem is I can't find an affordable serving dish to turn it out on without cutting it in half. For this dessert, not an issue, but I finally bought a tray just a little too short. Well, I can cut off just one end to make it fit - duh.
