Preheat the oven to 350-degrees and grease a 9”x5” loaf pan with butter and flour.
In a medium-sized bowl, whisk the flour, salt, cinnamon and baking soda until well combined.
In a large bowl, whisk the eggs, oil, water and vanilla until all ingredients are emulsified and well combined.
Add the sugar, banana and whisk to combine.
Dump the dry ingredients into the wet ingredients and mix, until just combined.
Pour the batter into the prepared loaf pan and bake until a toothpick comes out clean when inserted in the center, for 55-65 minutes.
Let cool on a rack for 20 minutes before carefully removing the loaf from the pan; cool completely.
Wrap well in aluminum foil and store, at room temperature, for up to 5 days.
