Yes. I love the taste the butterscotch chips add, and I like to use half butterscotch with half semi-sweet chocolate chips. I have included this as an option in the recipe. Butterscotch chips seem not to melt as well as they did years ago. So if you go with butterscotch chips, in the end, you will need to spend a few minutes smashing them to get the last few to combine. If you use butterscotch chips, get a good brand that melts better than generic.
