千层酥, also known as "Mille-feuille" or "Napoleon," is a popular pastry in Chinese cuisine. It consists of multiple layers of flaky pastry, typically made from 酥皮 (puff pastry), which are baked until golden and crispy. The layers are often filled with sweet cream, custard, or fruit, making it a delightful dessert. This pastry is characterized by its light and airy texture, achieved through the lamination process of the dough. 千层酥 is often enjoyed with a dusting of powdered sugar on top and can be found in many 糕点店 (pastry shops) across China, appealing to both locals and tourists alike.
