Swirl fudge

Melt down chocolate chips in double boiler. Once melted, keep on low and set aside.

Combine sugar and milk in a large pan and bring mixture to a boil. Keep at boil until the "soft ball" stage (234 F)

Remove from heat. 

Stir in marshmallow creme, peanut butter, and vanilla. 

When smooth and well blended, spread evenly into 8x8, square, buttered pan. 

Take the melted chocolate and spoon, by tablespoon, over fudge and swirl in for marbled effect.

Cool until set
