Cinnamon Roll Cake

I made this Cinnamon Roll Cake that has been on my menu plan for the last few weeks.  It was delicious!  Tastes just like a cinnamon roll with a lot less work, particularly no yeast or rising required.  The only change that I made was to reduce the butter in the brown sugar mix placed over the cake down to 1 stick, and I didn't miss the extra stick at all!  This would be a great, less fussy, substitute for cinnamon rolls at a brunch!
