This creamy peanut butter fudge is fast and easy. We use the old Fantasy Fudge recipe, adapting it by replacing the chocolate with peanut butter chips and adjusting the butter and milk quantities to make up for the addition of peanut butter. Since we believe things are always better with chocolate, we made a chocolate layer first (using the original Fantasy Fudge recipe) and topped it with this peanut butter fudge.
