Starbucks' Secret Barbie Drink Recipe is a frappuccino that is not listed on the menu, so be sure to request it! This version features strawberries, acai, coconut milk, vanilla syrup, dragon fruit, ice cubes, and whipped cream, all in a gorgeous pink hue reminiscent of the Barbie movie starring Margot Robbie and Ryan Gosling, directed by Greta Gerwig.
