Baklava is a layered dessert made of filo pastry sheets, filled with chopped nuts, and sweetened with syrup or honey.

Filo is a very thin unleavened dough used for making pastries such as baklava and börek in Middle Eastern and Balkan cuisines. Filo-based pastries are made by layering many sheets of filo brushed with oil or butter; the pastry is then baked.
