If you are a google searcher who was trying to find a banana cake, then I'll cut straight to the chase. The best banana cake in all the places I've traveled is made by the British ladies at a little cafe called Through The Looking Glass on the island of Koh Tao, Thailand. It will knock your socks off, stuff you like a pig, and you will cry a little bit when you are too full to continue indulging in its perfection. You won't even care when you've gained five kilos after eating it because it was just that good.
