Holiday Mint Fudge

1 7 oz jar mashmallow creme
1 1/2 cups sugar
2/3 c evaporated milk
1/4 c butter or margarine
1 12 oz package (2 cups) semi-sweet chocolate morsels (I use milk chocolate)
1 tsp vanilla
1 c Keebler Fudge Shoppe Merry Mint Patties, chopped

Line an 8X8 inch pan with aluminum foil, extending foil over ends of pan. Lightly coat with nonstick cooking spray. Set aside. In a heavy 3-quart saucepan, combine the marshmallow creme, sugar, evaporated milk, and butter. Cook stirring constantly, over medium heat until mixture comes to a full boil. Reduce heat to medium-low. Gently boil for 4 minutes, stirring constantly, remove from heat. Stir in chocolate morsels and vanilla until melted. Fold in Keebler Fudge Shoppe Merry Mint Patties. Spread in prepared pan. Cool. Refrigerate until firm. Cut into squares. Serve at room temperature.
