Cerberus did not bite at the honey cake.
There are some myths that mention Cerberus and honey cakes. For example, in the Aeneid, a Latin epic poem, the Sybil of Cumae threw a honey cake to Cerberus to make him fall asleep and let Aeneas pass1. In the story of Cupid and Psyche, Psyche was advised to carry honey cakes to distract Cerberus on her quest to the underworld. Honey cakes were also used as offerings for the dead in ancient Greek tradition3. So, it seems that honey cakes have a symbolic connection to Cerberus and the underworld in some myths.
