I found this recipe years ago, and it got rave reviews, but I lost it and have looked for it ever since. Only 3 ingredients, VERY simple, and it generously frosts a 13 X 9 pan of brownies or Cake. Works best when slightly warm. I usually use it on brownies, (but usually have a little left for on top of ice cream)....Feel free to experiment....You can use semi sweet, dark, or milk chocolate, and you can garnish the top with nuts etc, but move quickly before it sets up all the way and your garnish won't "stick".
Onr try and you will be hooked on the simplicity and the great flavor!
