Left-Over Mashed Sweet Potatoes Turned into MUFFINS!

We had some left-over Mashed Sweet Potatoes so I decided to make these Sweet Potato Muffins minus the Cranberries, since I didn't have any. I had my hubby taste-test them and he determined they were yummy before I took them to work. They were a HUGE HIT and VERY appropriate for an After-Thanksgiving Treat!
