It has happened to me several times. My mom sends me bananas from her produce and before I know it they are getting ripe too quickly for me to eat them all. I would salvage some for a smoothie but invariably I would end up tossing some away.
Not anymore. I have made a decision not to ever throw out another overly ripe banana. Only two days ago I made my first bread from scratch and it was a Banana bread using my ripe bananas.
So next time before you toss them, think of how to use them to create something yummy.
