I copied this recipe off the back of a jar of marshmallow cream. The recipe was for chocolate-walnut fudge. I just change the flavor of the candy chips for different flavors. It is a no fail recipe and always comes out the way you think fudge should.
There will come a point in this recipe where you think you can't possibly add any more flour. Your mixer, if it's a small one, may even become alarmingly warm. But push on and all your hard work will be rewarded with some of the tastiest and most comforting cookies I have come across. They're great for dipping in a cup of tea or just for snacking on. I particularly like to make them to give away at the holidays.
