This is a recipe made by all of my family members. It's easy; and even better, it's good!
2/3c carnation milk
12oz package chocolate chips (I use semi-sweet)
1oz jar fluff-or- 2c mini marshmallows
1c chopped nuts (optional)
Combine sugar, margarine and milk. Bring to a full rolling boil over medium heat. Boil for 5 minutes, stirring constantly. Remove from heat and stir in chips, marshmallows, nuts, and vanilla. Cool at room temperature.
