Notch has stated via twitter that the recipe for cake will be 3 milk, 3 sugar cane, and 3 wheat.[1] It is unknown what slots the ingredients will go in, and Notch later said that he was considering revising the recipe to include eggs. To allow for sugar, Notch has stated that he "retconned the bamboo to be sugar canes".
Notch finished coding cake to Minecraft on January 11th, 2011, and it will be released on January 13th, 2011.[2]
