you can make all kinds of cakes in a tube cake pan.. like pound cakes, they're baked all in one piece.. I make pumpkin cake this time of year and it bakes in a bundt-type pan, it could go in an angelfood pan and look more cupcake-like just as easily.. I haven't ever tried to make a from a box cake in all one piece but.. I don't have much experience with cake from a mix at all.. I expect you could probably do it. they tend to bake for about an hour at 325-350.. test 'em with a toothpick halfway between the side and the tube part to make sure it's done, should be OK..
pound cake would be tasty, though.. and sure to work.
