Animal cracker

An animal cracker is a particular type of small cracker or cookie baked in the shape of an animal, usually an animal one might see at a zoo or circus, such as an African lion, tiger, bear, or elephant. The most common variety is light-colored and slightly sweet, but darker chocolate-flavored and colorful frosted varieties are also sold. Although animal crackers are made with a layered dough like crackers, they are sweet like cookies.

Other animal-shaped crackers and cookies are popular, such as Teddy Grahams, Goldfish, Hello Panda, and Koala's March. These differ from traditional animal crackers in flavor and assortment, and though not usually called animal crackers, are still considered animal crackers.
