This is a light pie with a different twist using the marshmallows. My daughter has been making this for years as this was one of the first desserts she learned to make and has been making it since. Quite tasty!
In double boiler, place the milk, Hershey bars and marshmallows. Melt the mixture and then remove from the heat. Fold the whipped topping into the chocolate mixture. Pour into the pie crust and chill for at least 3 hours. Enjoy!!
