Mocha Cookie Crumble Frappuccino (590 Calories)
Tied for the top spot on the list is the Venti Mocha Cookie Crumble Frappuccino with 590 calories per serving. The 24-ounce drink also contains about 140 mg of caffeine, which should help keep you awake if you can finish it all.
The drink features rich mocha sauce, vanilla syrup, and Frappuccino chips that are blended with Frappuccino roast, milk, and ice and topped with whipped cream and cookie crumbles. The combination sounds great, though the calorie count may make it a bit less enticing.
