Starbucks Secret Menu: Biscotti Frappuccino
Buy a piece of biscotti and ask the Barista to blend it with your choice of Frappuccino.
Depending on the store, this may or may not be possible as not all locations will blend a food item in. If not, break up the biscotti yourself and throw it in to the Frappuccino. Don’t forget to ask for a spoon!
It adds tiny cookie chunks that make your frozen coffee a delicious crunchy treat.
