This is the cheaters way, but it’s awesome and quick.
2 large cans of Yams
1 cup margarine
½ cup brown sugar
½ c to ¾ cup cream
Small bag of mini marshmallows
Boil yams in their juice until hot. Remove and drain. Add margarine, brown sugar, cinnamon and salt. Mix with a hand mixer adding the cream a little at a time until smooth. Taste and if need be add more brown sugar. Pour into a baking dish and set aside, even refrigerate if you’re not serving within the hour, but before baking bring back up to room temp.
Bake at 350 degrees for 25 minutes. Add marshmallows to cover and broil for 1-2 minutes. Watch very carefully and make this the last thing you’re baking before serving. The marshmallows will burn very easily.
