I've tried so many fudge recipes, and honestly, the best one I've ever come across is the one on the back of the Marshmallow Creme jar. You can follow that recipe, and then in place of the semi-sweet chocolate chips, you can use whatever you like, for instance, white chocolate chips, or peanut butter, dark chocolate, whatever. I've also added stuff like broken pretzels to the mix. I always get rave reviews when I make this recipe.
