Classic French Napoleon
The Napoleon is a pastry made of many layers of puff pastry with filling alternating the layers. The topping may be simply powdered sugar, or a layer of fondant, often with strings of chocolate drawn into a chevron design.
In Italy, where the pastry is thought to have originated in Naples, it is called mille foglie (thousand leaves), and contains a similar layering like the mille-feuilles of cream, pastry cream, and fruit preserves.
A traditional napoleon is filled with plain pastry cream but if desired you may add a thin layer of fruit preserves such as seedless raspberry or strawberry jam or preserves to the filling.
