Not totally what you might have in mind, but this recipe looks promising through and through :http://www.manifestvegan.com/2010/11/pu ... mon-rolls/
A search for gf vegan cinnamon rolls seems to only lead to the recipe you posted, which actually sounds better than some of the others based in corn or oat flour, something foreign to me. Although, sorghum gives a bit of a hearty flavor is it's in a large enough quantity, so in care you want one that isn't based in that, here it goes:http://gliving.com/a-classic-cinnamon-roll-gluten-free/
and there's this apple cinnamon roll one:http://www.wikihow.com/Make-Gluten-Free ... amon-Rolls
and a variation on the one you shared:http://allergicadventures.com/2011/10/1 ... ree-vegan/
enjoy, and if you try one, I'd love to hear how it turns out. they may be on our weekend feast menu this week, too.
