If you want cinnamon rolls that are similar to the kind made with all-purpose flour, then yes, the psyllium husk is the magic solution. If you don't mind a cinnamon roll that has more of a biscuit consistency, you can use an extra egg as a substitute for the psyllium gel. (The egg will replace the 3 tablespoons of psyllium plus the extra 3/4 cup water you would mix it with.)
