Combine sugar, butter, and evaporated milk in a pot.
Bring to a full rolling boil, then after the boil cook for 5 minutes.
You want to keep a constant stir.
Remove from heat and add the 1 cup peanut butter, vanilla, and marshmallow creme.
Stir until well blended. Pour into a greased 9 x 13 baking pan.
Allow to cool and set until firm.
Enjoy!
