Preheat your oven to 350°F (175°C). Grease a 9x5" loaf pan and line the bottom with parchment paper, letting the paper hang over the long sides. Set the pan aside.

In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.

In a large bowl, cream together the butter and sugar until the mixture is light and fluffy.

Whisk in the eggs and vanilla extract until everything is well combined.

Mix in the mashed bananas. The mixture might look a little grainy, which is perfectly normal!

Add the dry ingredients from the medium bowl and mix until just combined. Be careful not to over mix!

Pour the batter into the prepared loaf pan.

Bake in the center of the preheated oven for 50 to 60 minutes. The top should turn a rich brown color, and a skewer inserted into the center should come out clean with a few moist crumbs.

If the outside is browning too quickly, loosely cover it with aluminum foil and continue baking until fully cooked.

Once done, cool the banana bread in the pan for about 15 to 20 minutes. Then, transfer it to a wire rack to finish cooling before slicing and serving.
