I know where I SAW some complementary donuts, but can't say I've seen any Cinnamon rolls.  Have you tried your lodcal bakery? ;-D

But seriously, what you need is a compact spiral with a crust like texture.  I would think that Trekkigirrrl could whip up something like that in a jiffy.  Send her an IM and see what she says.
