Preheat oven to 350 degrees. Grease and line a 9 x 5 baking tin with parchment paper with some overhang to allow for easy removal from tin.
Sift the flour, baking soda, baking powder, cinnamon, nutmeg and salt together in a large bowl.
Mix the eggs, sugar, bananas, vanilla extract and oil together in separate bowl. This is what mine looked like after thoroughly mixing.
Add the wet ingredients to the dry ingredients, taking care not to over mix.
Transfer to greased and lined tin and bake for 50 to 60 minutes or until a toothpick inserted in the middle comes out clean.
Allow to cool in tin for about ten minutes and then move to cooling rack to cool completely.
