Fantasy Fudge from Grandma Vera Barrus Wanlass

Here is the recipe:
3 cups sugar
3/4 cup margarine or butter
2/3 cups evaporated milk
2 cups chocolate chips
1 7 oz. jar marshmallow creme
1 cup chopped nuts (I used walnuts)
1 teaspoon vanilla

Combine sugar, margarine/butter, and milk in pan bring to a rolling boil. (Do not cook on high to get it to boil! That was Eddie's idea!) Cook over medium heat. Stir constantly. Pull up a chair...it takes a while to get it to boil on medium heat....but that's how you don't get grainy fudge!!! Once it boils, boil for 5 minutes stirring constantly. Mixture scorches easily! Remove from heat. Stir in chocolate chips until melted. Add marshmallow creme, stir until incoporated! Add nuts..stir until mixed well! Add the vanilla! I like this part because it makes the fudge shine!!! Beat until well blended! Pour into greased/buttered 9 X 13 pan. Let it cool! Cut into squares. Makes 3 pounds.
