For this recipe, you will need a good size pot that you can use a mixer in.
Spray a 9x13 pan with Pam and set aside
In your pot, combine sugar, milk and butter. Stirring constantly, cook over medium heat until you get to the soft-ball stage (238 degrees) NEVER SCRAPE the sides of the pan while stirring. Drop just a drop of this mixture into cold water. It should make a little ball and then you know the mixture is ready. If it bleeds into the water, it hasn't been cooked enough.
Remove from heat but leave in your pot. Add all chocolate chips, marshmallow creme and vanilla. Beat with a hand mixer until smooth and creamy.
If desired, stir in the nuts with a large spoon.
Pour into your sprayed 9x13 pan. Let cool.
Cut into serving size pieces and enjoy!
