Five Pound Fudge

4-1/2 c Sugar
12 oz Can evaporated milk
1/4 lb Butter
1 Jar marshmallow creme
12 oz Semi-sweet chocolate chips
12 oz Milk chocolate bar
2 c Chopped pecans or walnuts
2 ts Vanilla

Cook sugar, milk, and butter to soft ball stage (234 degrees on candy thermometer), stirring constantly. Take off the heat and add the remaining ingredients. Stir quickly and thoroughly to blend. Pour into a large baking pan or dish (I lightly butter it first). Cool. Cut into squares and store in refrigerator.
