Chocolate-filled Tāngyuán is a decadent and indulgent variation of the traditional rice balls. The dough is filled with a rich and gooey chocolate filling, which melts when the rice balls are cooked. The warm and melty chocolate center creates a delightful contrast with the chewy rice balls. This dessert is perfect for chocolate lovers who want to take their Tāngyuán to the next level of deliciousness.
