Homemade Horton Hears a Who Cake My cousin's daughter just turned one and they were throwing a Horton Hears a Who party. My cousin approached my and asked me if I could make a Horton Hears a Who cake (elephant cake) for the party. I love to bake and usually make the cakes for friends and family's parties. My cousin saw a few ideas of elephant cakes on this website and sent them to me. I absolutely loved this cake and it was a hit at the birthday party!! Let me know if you would like to make this cake and I will send you the detailed instructions.
