Using the Perfect Manhattan template, I added a touch of Chambord to stand in for the jelly and the sweet part of the sweet vermouth, dry vermouth, and cut back the bourbon ratio just a bit to add in the flavored whiskey. This is a refined version of most peanut butter whiskey drinks - and one a bourbon lover is most likely to enjoy as it plays off the nuttiness of the base bourbon and the butterscotch flavor from the flavored whiskey.
