I made this for Thanksgiving. I love sweet potatoes but my family does not, so I wanted to try something other than the standard yams and marshmallow dish.

Not only is this an easy dish, but my entire family LOVED it! Even my mom who hates sweet potatoes. I didnt have the pan size required, so I split the dish in half and used 2 7X12 inch baking dishes. It cut the cooking time by 30 minutes - which was nice because I was way behind schedule.

I would definitely make this again - before thanksgiving roles around.
