This is dessert showing off. Take ice cream, which is already sugar and cream, then coat it and dunk it in hot oil so it picks up another layer of fat and crunch. The frying alone adds serious calories on top of the ice cream inside. That is how a single ball lands at around 360.
Honestly it is delicious and a fun thing to order once in a blue moon. Just do not kid yourself, this is the heaviest dessert in the lineup at 18g of fat a piece. Bro one of these is basically half a burger in dessert form. Share it, or have one and skip the second drink.
