Preheat oven to 350°F (180°C) and spray the bottom and sides of a 9x5x3 inch loaf pan with non stick cooking spray or brush with melted butter.
Whisk all dry ingredients in a medium bowl and set aside.
Into another larger bowl, add all wet ingredients and whisk until very smooth. Add the dry ingredients and whisk until just combined. Tip: Use heavily speckled bananas for deep fruity and caramelly flavor.Pro tip: Don't over mix! It’s ok if some traces of dry flour are left behind. The more you mix, you'll end up developing gluten in the batter, and you'll have a denser, almost chewy loaf.
Transfer batter into the prepared pan, smooth top and sprinkle walnuts on top.
Bake for 45 to 55 minutes or until a tooth pick inserted in the middle comes clean. Place pan on a wire rack and cool completely.Tip: If during baking, the top of the eggless banana bread looks like it is getting too brown, cover it loosely with aluminum foil and continue to bake until done.
Notes
Banana – use ugly over ripe bananas (dark yellow skin with lots of brown spots).Vegetable oil – Use a flavorless oil like vegetable or corn oil.
