Baking is a method of preparing food that uses dry heat, normally in an oven, but can also be done in hot ashes, or on hot stones. The most common baked item is bread but many other types of foods are baked. Heat is gradually transferred "from the surface of cakes, cookies, and breads to their center. As heat travels through, it transforms batters and doughs into baked goods and more with a firm dry crust and a softer center".

Baking may also refer to the preparing of all kinds of desserts and sweets (interchangeably with confectionery). The professional that domains this area of expertise is the baker.
