These were super awesome. I have no idea how they keep, though, because we ate all of them almost immediately. I mixed the cinnamon with the egg whites and it seemed to stick really well. :)
These tasted really good. A little labor intensive, but worth it if you have the time. I need to get more adept at the rolling part; mine were a little thick :) I'll being trying them again, though! ( I used Splenda for the topping, and brown sugar for the dough, since I rarely have granulated sugar anymore) P.s. These are a little like a bagel.
