Ooh, I used to make Hummingbird Cakes. The recipe is in an old Southern Living cookbook. Sorry, I have no idea if it can be found online but it’s yummy.
-— Wait, this link says it’s the most requested Southern Living recipe so hopefully this is the real deal. It sounds like what I remember:

I’m sure that’s the recipe I used. It’s very similar to a carrot cake I make, except for the bananas. That carrot cake is to die for. Made it for Thanksgiving this year. Thanks for posting. Might bring it again this year.
