Sweet Potato Cranberry Muffins

Just trying to find different flavors out there that my picky three and a half year old will eat and that is healthy. My one year old will pretty much eat anything you set in front of him...for example he downed one of these muffins in less than two minutes flat.

** I mashed a whole Sweet Potato and got about 1 1/2 cups of mashed potato. Going to freeze these in half cup portions so I can make these again another time and not need to run out and buy a sweet potato.
