Preheat the oven to 185 C.
Grease and flour your baking tray and have it ready. Tap to remove excess flour. I used a 6-inch Loaf tin.
Pulse the ripe bananas to a puree, transfer to a mixing bowl.
Add sugar, oil, vanilla essence, baking powder, baking soda and whisk well.
Let it sit for 5 mins, then add the wheat flour and mix in gently.
Finally, fold in the chopped walnuts and pat them down.
Bake for 30 to 40 mins at 185C or until the toothpick inserted comes out clean.
Mine got done in 30 mins, I baked it further for 5 more mins and left it to rest for 15 mins.
