Khaja is a popular sweet of Bihar and eastern Uttar Pradesh, which is usually relished during religious festivals. To make khaja, refined wheat flour is mixed with sugar and oil to form a layered dough. The dough is then stuffed with dry fruits and lightly fried in oil until crisp. The crisp layered croissants are then dipped in a sugar syrup until they absorb it completely. The delicious sweet is one of the most important food items of the Chhatt Puja Festival in Bihar.
