The quest continues. The girls told us there is a secret menu at Starbucks and they have Butterbeer.
Ask for a cream based vanilla bean Frappuccino with one or two pumps of caramel syrup and one or two pumps of toffee nut syrup and topped with caramel drizzle.
Which we did with two pumps of each. It's too sweet but sort of close. Might be worth trying again with one pump of each. We were there for happy hour so half price ;)
