These Low Calorie Ice Pumpkin Lattes are just 36 calories! They are also low carb and low in sugar, and taste better than popular coffeehouse versions.I use REAL PUMPKIN in these lattes, this boost both the flavor and the nutrition. But you can omit it if you like. Special Tip: You can use your preferred milk and sugar. The ones chosen are the lowest in calories, but cows milk and regular sugar can be used if you prefer.
