Ice cream is definitely an indulgence, which means that it’s not a bad idea to find out exactly how much a serving size is if you like to have it on a regular basis. Generally, a serving is 1/2 cup, according to the carton. According to Hungry Girl, a serving is a lightly packed 1/2 cup and not the full measure.
The only question is what exactly a lightly packed half-cup of ice cream looks like. The term is often used to describe baking ingredients like flour and brown sugar, both of which will either “settle” into a cup or remain “lightly packed.” Solid things, such as chocolate chips, don’t exactly “pack” – they either fill the cup or they don’t - and this category includes unmelted ice cream. Wouldn’t it be easier just to say that a serving size was a full 1/3 cup, rather than leaving consumers to estimate exactly how much less than 1/2 cup their serving should be?
I’m not about to break out my kitchen scale to weigh ice cream, so I’ll try to stick to the scoop rule where one normal-sized scoop is a serving and you have plenty of room, both size-wise and calorie-wise, for a cone and toppings.
