Remarkable Fudge

This is my dad's favorite fudge. My mom found the recipe in the 1960's in a cookbook she got with her S&H food stamps. It's super good and doesn't stay around long that's for sure. It was always a favorite of the UPS guys and our mailmen too!

Remarkable Fudge
4 cups granulated sugar
1 can evaporated milk
1 cup butter
1 pint marshmallow cream
1 pkg semi-sweet chocolate chips
1 tsp vanilla
1 cup chopped nuts (my dad likes walnuts)

Add sugar, evaporated milk, and butter into a heavy 3 qt sauce pan. Cook over medium heat, stirring to soft ball stage (236 degrees on a candy thermometer.) Remover from heat. Add chocolate Chips, marshmallow cream, vanilla, and nuts. Por into a butter pan, spread out evenly. Cool to set. Then cut in to squares to serve.
