Here is the real difference that will make you smile. Ice cream usually comes pre-portioned in a pint or a scoop shop where the guy with the scoop stops.
Frozen yogurt, on the other hand, is a choose-your-own-adventure that often spirals out of control. You grab that giant cup, swirl in six different flavors, and then hit the toppings bar.
By the time you add gummy bears, cookie dough, and hot fudge, you’ve accidentally created a 800-calorie monster. Ice cream rarely lies to you like that. It just sits there, quietly, in its two-scoop glory.
