Amazing Cinnamon Rolls from Sourdough Starter

So just a quick note to let you know that you can make amazing cinnamon rolls pretty quickly with sourdough starter!  When I want to make cinnamon rolls I mix up a batch of sourdough bread with only white flour the night before.  Then in the morning I roll out the dough and fill it with the filling from this recipe:

Filling 
4 tablespoons butter
1 1/3 cup brown sugar mixed with 1 tablespoon cinnamon

Then I let it rise again in the pan, and bake at 350 for about 30 minutes.  When they come out I put this icing on: 

Icing:
1 teaspoon milk
1 1/2 cups confectioners sugar
4 tablespoons (or less) butter, softened
1 teaspoon vanilla

I never used to make cinnamon rolls because I hated to make the dough and didn't like rolling it out either.  But now that making the dough is already a part of my bread-making routine, it's easy to do.  So these have become my go-to when I want to impress or bless, because I always have the ingredients on hand.  And they freeze great.   The filling and icing recipe is from this site: http://moneysavingmom.com/2010/01/bread-machine-cinnamon-roll.html
