Prepare a 9 by 5 by 3 inch loaf pan with cooking spray, melted butter or oil. I like to use parchment paper. Just spray the pan so the paper will stick. I then spray the paper.
Whisk together the flour, baking soda, and salt in a medium bowl.
In a large bowl, mash bananas, keeping them a little bit chunky (my preference). Add the eggs, sugar, and oil and mix until smooth.
Add the dry ingredients to the banana mixture and stir until just combined (don't over mix).
Pour batter into prepared loaf pan, leveling the top of the batter if needed.
Bake for 55 to one hour and 10 minutes, depending on your oven. The center of the bread should be set, not jiggly. If the top of the bread is browning too quickly, cover loosely with foil.
Let bread cool in the pan for about 10 minutes, then transfer to a cooling rack to cool completely.
Notes
Since ovens are different, cooking time will vary. Check on your banana bread at the 50 minute mark.
Don't open the oven door before as it will cool the oven temperature.
Mix this recipe by hand. There's no need to use a hand or stand mixer.
I didn't add any flavorings, but you might like to add some pure vanilla extract.
