The Bitter Teeth cake was created by Chloe Bird, who followed an original t-shirt design by Threadless. She cast a silicone mold of a human skull, and used it to create the face and jaw of her cake out of delicious milk chocolate. The back of the skull was made from baked sponge cake and clued to the front of the skull with even more milk chocolate. Before covering the whole thing in molten chocolate, Chloe carved the details of the skull using dental equipment. The creepy teeth were painted with dark chocolate.

As you may imagine, its creepy look didn’t save the Bitter Teeth cake from the hungry mouths of Chloe’s work mates, who were all over it the moment she unveiled it.
