Here's a special tip from me to you: Don't attempt to substitute regular marshmallows for marshmallow cream because you accidentally didn't buy a large enough jar. It will make your dip lumpy and very difficult to actually dip into. Not that it happened to me, or anything...
12 fun size Butterfingers
8 oz cream cheese, softened
10 oz marshmallow cream
Mix cream cheese and marshmallow cream together in a bowl. Chop 10 Butterfingers into chunky pieces and pour into bowl. Combine. Transfer to serving dish. Chop remaining 2 Butterfingers and sprinkle on top of dish.
Best dippers: graham crackers, apple slices
