As promised, here's the recipe for the Banana Bread I could make in my sleep. I think I've been making this very regularly for about 12 years and it has only not worked out once. You just need really old and disgusting bananas.
Line a loaf tin (the one I use is 21cm long, 11cm wide and 7cm high or 8 x 4 x 3 inches approx) with baking paper and preheat the oven to 160c (fan)
2-3 revolting, old mashed up bananas
2 eggs, lightly beaten
1 teaspoon cinnamon (although I might omit this if I decide to use chocolate chips)
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1/2 dark brown sugar
1 1/2 cup flour (I quite often do half plain flour and then the other half something more wholesome like either spelt or wholemeal flour)
1/4 cup of vegetable oil, but not olive oil. I usually use canola.
1 teaspoon vanilla extract.
1. Mix the sugar and oil together.
2. Add the eggs, mashed banana and vanilla until it it all very well combined.
3. Add all the dry stuff - the flours, baking powders salt etc. until it is just combined - don't over mix it. At this point add chocolate chips if you are feeling crazy or just leave it plain.
4. Pour the batter into the loaf tin and bake in the centre of the preheated oven for about 45-50 mins or test with a skewer until it comes out clean. Leave it in the tin for 5 mins and then turn it out onto a rack to cool.
