Candied Yams

4 Pounds sweet potatoes peeled and cut into chunks
1/4 cup butter
1/4 cup brown sugar

In a saucepan, combine butter and brown sugar. Cook until well mixed and melted and then add 1 cup mini marshmallows. Stir frequently until marshmallows are melted. Mix syrup mixture with sweet potatoes and mash while combining. You can leave it as chunky as you like.
