What best defines the texture of a cake?

The texture of a cake is best described as soft and fluffy. This characteristic is often achieved through the combination of ingredients and proper mixing techniques, which incorporate air into the batter, resulting in a light texture. A well-made cake rises during baking, leading to an airy crumb structure that is enjoyable to eat.

In contrast, the other options describe textures that are not typical of cakes. A crunchy and hard texture might be better associated with certain cookies or crackers, while a savory and chewy texture is more characteristic of breads or pasta. A hard and dry texture is often indicative of overbaking or using incorrect ratios in the recipe, which can lead to undesirable results. Thus, "soft and fluffy" aptly captures the ideal texture one aims for in cakes.
