Mix together everything except the butterscotch chips.
Once combined stir in the butterscotch chips.
Drop onto a cookie sheet in 1 inch scoops. Keep it small these spread a lot!
Bake at 350F for 8-10 minutes.
Remove from oven and immediately top each with an unwrapped peanut butter cup.
The heat from the cookie should melt the chocolate and when it does take a knife and smoosh it down to make the marbled look. If your cups don’t get spreadable you can pop the cookie sheet back in the oven for a minute.
Notes
I love a good Christmas cookie exchange but this time of year is so busy that I’m thankful for recipes like this Cake Mix Peanut Butter Chocolate Cookies recipe.
