I've made Gluten-Free Girl and the Chef's cinnamon buns 3 times now and they are marvelous! The second time they were more like cinnamon pieces because the dough was too wet but they were delicious anyways. This last time I remembered to take pictures.
I think I overcooked them a bit and didn't put enough sugar in the filling - but regardless, they were all gone quite quickly.
Verdict: highly recommended!
