Cinnamon Rolls NOT rising (or rising really slowly) could be caused by a number of reasons. Your yeast was not fast-acting, your yeast was old, you kneaded in too much flour, your kitchen was on the colder side, etc. etc. If you're really concerned about it, simply double the yeast to have some extra insurance. These rolls are made with a very enriched dough (see my note above about enriched doughs) which make it a slow rise. This is totally normal! Again, if you'd like to speed things up, simply double the yeast.
