Cake

Notch stated if Minecraft won the Mod DB 2010 "Indie Game of the Year" award, which it did, he would add cake to Minecraft.

Cake Heals every use, and may be used six times. Cake may be placed as a block and can be used to heal the player in that form, but will not return anything when broken.

Crafting
The recipe for cake is 3 milk, 2 sugar, 1 egg and 3 wheat. The Milk is replaced by Empty Buckets after crafting.
