Chichimbré (from English, "gingerbread") is a Mexican pan dulce, which is made mainly from corn or wheat flour, piloncillo, cinnamon, and yeast. When fresh, it has a texture somewhere between a bizcocho or sweet roll and a cookie.
One of the most popular forms of chichimbré is as cochinito de piloncillo, which is made with cookie cutters in the shape of a pig.
Word origins
Chichimbré is claimed to be derived from English "gingerbread," supposedly from workers that came to Huasteca in northeastern Mexico to work in the oil industry. I have not yet found a source that supports this claim conclusively but it appears to be widely accepted.
