We do have self rising flour here in the US. It might be the kind of thing you wouldn't notice if you never specifically looked for it, though. Or maybe not available in all locales, idk.
I use overripe bananas in banana bread because when I've used bananas that weren't overripe, the resulting banana bread just didn't have much flavor.
If your banana bread is too done on the outside and not done enough on the inside, I'd try turning the oven down about 25 degrees F. Or make banana bread muffins instead, since there's less space between the interior and exterior that way.
I rarely use a recipe that I'm happy with the first time. It seems there's always a tweak or two it could use imo.
