I love fudge too!

Making it just puts me in a Christmas mood. I use a marshmallow creme recipe too although it's slightly different than the one posted. Here's mine:
Remarkable Fudge
4 c. sugar
2 5-ounce cans (1 1/3 c. total) evaporated milk
1 c. margarine or butter (I use butter)
1 12-ounce pkg (2 cups) semisweet chocolate pieces
1 7-ounce jar marshmallow creme
1 cup chopped walnuts
1 tsp. vanilla
Line a 13x9 inch baking pan with foil (I have used parchment or wax paper too); extend foil over edges. Butter foil; set aside. Butter sides of a heavy 3 qt. saucepan. In it, combine sugar, milk and butter. Cook and stir over medium-high heat to boiling. Clip candy thermometer to side of pan. Cook and stir over medium heat to 236 degrees, soft-ball stage (about 12 minutes).
Remove saucepan from heat; remove thermometer. Add chocolate pieces, marshmallow creme, nuts and vanilla; stir till chocolate melts. Spread into pan. Score into squares while warm. When firm, cut into squares. Store in the refrigerator. Makes about 3 1/2 pounds.
Chocolate/Peanut Butter layered fudge (a huge hit amongst family and friends!)
Use above recipe but you're going to make two batches back-to-back. First you will make the peanut butter batch. For this you will just substitute Reese's peanut butter chips for the semisweet chocolate chips and omit the nuts. Spread that amongst two pans (I use one 13x9 and one 9x9 pan to make it a little thicker). Then immediately make a regular chocolate batch (omitting the nuts) and spread that on top of the peanut butter fudge. It is delicious if you want a layered fudge!
