In a word, no. We have had readers try it and they say it doesn’t turn out right. We haven’t tried it before, but I can tell you it won’t be the same. Some say that they have melted marshmallows down or used a recipe to actually make marshmallow fluff, but again, we haven’t tried this so we can’t tell you for sure that it will work. We like to keep things simple and always stick to this original fudge recipe.
