I've wanted to try the Birthday cake frappuccino for so long and today I finally get to taste it. The Birthday Cake Frappuccino Firstly, they dont blend a cake, add some cream and blend it. It's a variety of syrup with milk and ice (blended) The syrup includes( vanilla and hazelnut ) The first zip is good. Taste exactly like a cake. As for the cream, it is a velvety raspberry infused whipped cream. It's that not different from typical whipped cream. As you drink, the taste seems so get faker and faker. It gets a little too sweet. If you like hazelnuts and super sweet things this is the drink for you. -Stefanie
