I've been trying lots of grain free recipes lately, and this is easily the best one yet!
I thought I'd link to the recipe from Joyful Abode, in case you'd like to give it a try.
I didn't make the frosting, because I was out of cream cheese - I just brushed some melted butter on top, once they were out of the oven, then sprinkled the cinnamon sugar on.
The consistency was great.
I definitely suggest giving them a try, even if you're not worried about eating grain free - they're low carb if you'd like to think of them that way ;)
