A croissant is a classic French pastry made from layers of buttery, flaky pastry dough. The dough is rolled and folded multiple times to create dozens of flaky layers. It is typically shaped into a crescent shape and is often served as a breakfast pastry or as a base for sandwiches. Croissants are often enjoyed with coffee or tea and can be filled with a variety of sweet or savory ingredients such as chocolate, cheese, or ham and cheese. They are known for their crisp, buttery exterior and their light, airy interior.
