Starbucks is about to release a drink itâs calling the Unicorn Frappuccino. Starbucks baristas on Redditâs Starbucks page had been posting pictures of pink and blue powders teasing us on what is to come! The beverage is believed to be some combination of white mocha, mango, and the powder, topped with whipped cream and tons of sugar sparkles that come in a separate shaker. Okay we're in. We are DEF going to try this! The drinks is supposedly coming out this Wednesday!
