Add 3 cups sugar, 1.5 sticks ( 1 stick and a half of another stick) of butter melted and 2/3 can of canned milk in a 2 quart pan, bring to rolling boil, lower heat to medium and stir exactly 5 mins. Remove from the stove and add 1 12 oz bag of Chocolate Chips, 7.5 jar of Marshmellow Fluff ( do not used the creme kind of marshmellow) and 1 tsp of vanilla. Stir fast and quickly as you add the fluff and chocolate chips, do one at a time but quickly behind each other. Then pour into 13x9 pan, cool @ room temp and then cut. Makes 3 lbs..FYI: If you would like to make Peanut Butter Fudge add a cup of Peanut Butter instead of the Chocolate Chips.
