I have not had trouble with the Two Ingredient Fudge being soft, as someone mentioned. I use any canned frosting (except whipped) and any flavor of chips, even the ones that are in packages less than 12 ounces. I always store it in the refrigerator though, and I let it chill quite awhile before cutting it. I did try a quick fudge recipe that I think I like better. It tastes just like the old-fashioned fudge my mother use to make. The recipe may even have been one from here a long time ago?

Microwave Fudge

Combine in a large microwave-safe bowl:
3/4 cup butter
2 cups sugar
2/3 cup (5 oz. can) evaporated milk
Microwave on high for 5 minutes.
Add: 1 jar (7 oz.) marshmallow cream
1 cup chocolate chips
1 tsp. vanilla extract

Stir in and cook another 5 minutes on high, stirring half way through. Remove from microwave and stir till chips and marshmallow cream are melted. Stir in 1 cup chopped nuts (optional). Put into a foil-lined 9 inch square pan and chill until firm. Cut into squares. This is wonderful candy, and is VERY addicting! It ships well also.
