Here is the ingredient list that can be found on their website: Nonfat Vanilla Yogurt [Cultured Pasteurized Grade A Nonfat Milk, Agave Syrup, Vanilla Extract, Carob Bean Gum, Vanilla Beans, Pectin, Water], Mixed Berry Compote [Mixed Berries (Strawberries, Raspberries, Blueberries), Evaporated Cane Sugar, Water, Plum Puree, Cornstarch, Ground Coriander, Citric Acid], Granola [Whole Rolled Oats, Milled Cane Sugar, Rice Flour, Oat Flour, Expeller Pressed Canola Oil, Molasses, Honey, Natural Flavor, Salt, Barley Malt Syrup] As you can see, Starbucks uses a nonfat vanilla yogurt that is sweetened with agave. An easy substitute for this would be to mix a small amount of agave or honey in with plain yogurt.
