a present left in a baby's diaper as a result of their poopy being in the shape of a small chocolate cake
Tyler just smushed his diaper cake when he fell on his ass in the sandbox!

Stacked useable baby necessities (mainly diapers) shaped into a form of a cake. They make a lovely centerpiece or decoration for a baby's room. Almost all part of the cake may be utilized by mom and baby and may match the theme of a party or baby's room.
