Starbucks once held a contest for secret menu Frappuccinos In 2015, Starbucks temporarily offered a collection of what they called Fan Flavor Frappuccino beverages, including Caramel Cocoa Cluster, Cinnamon Roll, Cotton Candy, Cupcake, Lemon Bar and Red Velvet Cake. Then customers voted for their favorite during a 10-day contest. The winner was Caramel Cocoa Cluster, but it’s no longer on the official menu. You can order it now by asking for a regular coffee Frappuccino with three pumps of toffee nut syrup, plus whipped cream, caramel sauce and mocha sauce on top. 7
