Preheat the oven to 350ºF. Line one 8x4-inch pan or two mini loaf pans with parchment paper, leaving extra hanging from the sides so you can pull the bread later, or spray with nonstick cooking spray.
Add the banana, butter, sugar, vanilla, cinnamon, salt and egg to a blender jug. Blend until smooth. Add the remaining ingredients, flour and baking soda and pulse just to combine.
Pour the banana bread into the loaf pan and bake for 25 to 35 minutes until browned on top and cooked through. Check doneness by inserting a toothpick in the center and it should come out clean.
Remove from the oven and let it rest for 5 minutes before pulling it out of the pan.
Once cooled down a bit, pull the bread carefully with the hanging paper from the loaf pan, place it on a plate and enjoy.
Notes
The key to making the best banana bread is to use spotty ripe bananas. They provide the most flavor and sweetness, and will make your loaf extra moist.If you only have unripe bananas on hand, you can place them in a paper bag with an apple or a couple of tablespoons of sugar. The natural ethylene gas emitted by the apple will help speed up the ripening process.Be careful not to over blend the ingredients. Overmixing the batter too much can in a tough texture.For a quick and easy release from the pan, be sure to alway line your mini loaf pans with parchment paper.
