A traditional French puff pastry which is made in layers of crisp baked pasty separated by cream fillings. As a dessert the fillings may be made of puréed fruit, jam, preserves, whipped cream, or custard mixed with nuts that are typically baked as an oval or rectangular-shaped pastry with 2 to 7 layers. Mille-feuilles made into appetizers are generally filled with cheese instead of sweet fillings and served warm. The surface of this pastry is most often dusted with a sugared icing or powdered sugar. A name often used in reference to a Mille feuille is to call it a Napoleon, which may be due to the similarity to "Neapolitan" or another type of layer French pastry.
