There's one kind of fudge called Four Chip Fudge that's also yummy. It calls for milk chocolate, semi sweet chocolate, butterscotch and peanut butter chips. It has a complex flavor and is scrumptious.
Several years ago, Southern Living magazine published a recipe for microwave peanut butter fudge that was awesome. I let it get away from me. Maybe it's on their website.
Vanilla fudge is not just the name of a 60s rock group, but is also a legitimate fudge flavor. You need really, really top quality vanilla flavoring for this fudge, since that’s the dominant flavor. Use the best real vanilla you can find.
