In a small sauce pan add all the ingredients. Whisk together over low heat until melted. Dip cooled donuts or muffins into the frosting.
Since this recipe is coconut oil based it will never fully harden, but will stiffen up quite a bit depending on how much it is heated. It is easiest to dip and spread when it is warm. I allow the extra to cool fully and form it into balls and refrigerate for homemade truffles.
