Faced with over-ripe bananas, yet again, but wanting to try something different, I came across this recipe from Matt Tebbutt and BBC's Saturday Kitchen. It adds coffee and (optional) chopped chocolate to banana bread - of course I added the chocolate! This was a straightforward recipe to follow, and didn't give me any problems.
This made a pleasant enough loaf cake, but didn't convince me that any of the added flavours - chocolate, coffee and nutmeg - actually improved the basic premise of banana bread, which is that you want it to taste mostly of bananas.
I've just noticed that when I used chocolate in a banana cake once before, I didn't really like the result that time either, but thought the issue was too much chocolate. I'll be sticking to adding dried fruit and/or nuts in future.
