Peanut Butter Fudge

3/4 cup butter
3 cups sugar
2/3 cup evaporated milk
12 ounce package of peanut butter chips 
or 
6 ounce peanut butter chips and 6 ounce semi sweet chocolate chips
1 teaspoon vanilla
7 ounce jar of marshmallow cream
1/2 cup chopped peanuts

In a glass bowl, melt 3/4 cup butter on high until melted.  Add sugar and evaporated milk.  Mix it up and then microwave on high for 5 minutes or until it starts to boil.  (Stir it mid way and scrap edges so it doesn't turn sugary.)  Microwave again another 5 and 1/2 minutes, stirring mid-way through.  Add peanut butter chips or the 1/2 chocolate chip/1/2 peanut butter option (they are both excellent).  Add vanilla, marshmallow cream and chopped peanuts.  Pour into a buttered 9x13 pan.  Cool and eat.  (Makes 3 pounds of candy)
