cracker

Crackers are thin, crisp baked foods usually made from flour, water, and fat, often with salt, seasonings, or other flavorings. 

Savory crackers may be plain, salted, seeded, herbed, or cheese-flavored and are commonly served with cheese, spreads, dips, soups, and appetizers. 

Sweet crackers, such as graham crackers, contain sugar or other sweeteners and may include ingredients such as honey, cinnamon, or whole-grain flour. They are eaten as snacks and are also used in desserts, particularly crushed to make pie and cheesecake crusts or layered with other ingredients.
