Starbucks Caramel Frappuccino Light You Can Now Make at Home! This Starbucks creation, which cuts the fat, carbs and calories of the original Frappuccino is a top-seller with coffee house regulars. My favorite is the caramel one. The skinny for 1 serving is 132 calories, 1.8 grams of fat and 4 Weight Watchers POINTS PLUS. Have fun skinny sipping!!!
