The individual cakes will shrink a bit after removing them from the oven. This is normal and will not affect the texture — they will still be light, moist, and fluffy.
Preheat oven to 325F.
In a bowl, sift the flour with baking soda, baking powder.
In another bowl, mix the eggs, vanilla extract, sugar, mashed banana until ribbon stage.
Add the flour mix to the egg and banana mix, mixing gently.
Once the flour has been incorporated, add the walnut (optional) and the oil.
Pour into a prepared muffin tin (with about 18 cups) and bake for approximately 25 minutes or until an inserted wooden toothpick comes out clean.
Cool on a wire rack and serve.
