I am a huge Diane Mott Davidson fan, as her book are fantastic as are her recipes from the books. I can't remember which book this is from though. This is my husbands favorite cinnamon roll recipe. It can also be made using Splenda products with good results. I will note the changes made when using Splenda at the end of the recipe. Prep time does not include the two 1 hour rises needed. The frosting is good but not neccessary to make these rolls a treat. It just depends upon how rich you want them. A side note, I made these for Xmas this year and only put in one envelope of yeast and even though they didn't rise as much as usual they still came out great...LOL.
