I don't know why I have such an addiction to butterscotch, but I do. I was looking for a quick and easy dessert to make and when I saw that this one had a butterscotch option, I jumped up off the couch and made them immediately. I brought them to class one night and one of the girls asked me if she could pay me to make her some...uh ...yea. They are that good. They are so ooey gooey. You will love them.
