I have made every kind of Peanut Butter fudge there is but here is a simple, but tasty, recipe that my family and I really enjoy. I found this recipe on the internet several years ago when I was craving some peanut butter fudge and only had the basic ingredients. You may want to use a candy thermometer, but I just boil the mixture for about 9 or 10 min. and drop a little of the mixture in a cup of cold water until there is a soft ball and it always has come out good for me. I also use butter instead of margarine and if I don't have milk I use Evaporated milk. I also use Peter Pan Peanut Butter--a family favorite. The recipe states if you want Chocolate Fudge to "add One Heaping Teaspoon of cocoa to the top four ingredients before cooking." I haven't tried the chocolate fudge version yet.
