A surge in demand for the Dubai-style chewy cookie known as 'Dubbi chewy cookie' (두쫀쿠) has led to a crowd-sourced map service that lists cafes selling the treat and their reported stock levels. The developer said he built the service after struggling to find the cookies for his girlfriend; cafe owners can apply to be listed and then log in to update inventory, though displayed stock may lag behind real-time. The dessert mixes kadayif (Turkish shredded pastry), pistachio spread, chocolate and melted marshmallow around a chewy cookie. Many shops sell out by mid-morning, prompting nicknames like 'Duketting' (두켓팅) comparing buying one to securing popular concert tickets. About 360 stores are registered so far. Critics warn the craze could be short-lived like past fads such as tanghulu (탕후루) or honey butter chips, and rising pistachio prices from global shortages may make the treats too expensive for some buyers.
