I found this recipe in a magazine and just had to try it.

I don't have any Rapid Rise yeast, so I just used regular yeast and only 1 package or 2-1/4 tsp.  I let it rest for an hour, instead of the 10 minutes, then spread the brown sugar cinnamon mixture on top and poked it in.  Then I covered it with plastic wrap and put it into the refrigerator. The next morning I pulled it out, let it sit for about half an hour to come to room temperature, and then baked as directed.  I baked it for about 5 extra minutes.
The icing was really good, but I made it a bit thick so ended up spreading it on instead of drizzling.  I think there was enough icing for a double batch, so next time I'm either making less icing or making more cake!  I really liked the flavor, though, and I'm thinking of using this icing recipe for my cinnamon rolls next time.  The butter just added something. 
Also, next time I will follow the Recipe Note and mix it in a separate bowl.  I can't figure out the reason for spraying the pan and then mixing the dough in it.  I will definitely be making this again - it was so good!
