There's really only two things to be done when bananas are totally past it.
One can feed them to the compost [ aka Rosie, Rowan, Ruby and Robbyn ]
one can make banana cake
Given that Ms Tara and her current knitting are venturing hitherwards from deepest, darkest Bendigonia this evening, I went for the cake option.
Sorry goat girls, you miss out.
Bewdiful Banana Cake:
2 1/2 cups of self raising flour
3 medium or 2 large over ripe bananas
1 cup castor sugar
3/4 cup of low fat milk
1/4 cup oil
1/4 teaspoon ground ginger
a shake of nutmeg [ optional]
Mash the bananas.
Mix all the ingredients and pour into a loaf pan.
Bake for 50 minutes in a moderate oven [ about 160C ] until an inserted skewer comes out clean. Let sit for 10 minutes before turning onto cake rack for cooling.
Ice [ frost ] if desired
Of course to do that you actually have to hold off on the eating until it's cooled down, so icing rarely [ as in NEVER ] happens around here.
