I made this cake for my 3 y.o. nephew Alexander. He has made up his own "Knock Knock" joke : Alexander "Knock knock" (with a british accent, don't ask me where or how!) me "Who's there?" Alexander "Banana" Me "Banana who?" Alexander "BANANA! hahahahahahahahah!" :) Too cute! So I made him this Banana flavored cake in the shape of a banana. I put a layer of French vanilla pudding in the middle (yum!) and the icing is banana/vanilla flavored buttercream.
