Preheat oven to 350°F and grease a 9x5 inch loaf pan.
In a large mixing bowl, mash the bananas with a fork. Add eggs, oil, both sugars, and vanilla. Stir until smooth-ish.
Add the flour, baking soda, and salt. Gently fold until no flour streaks remain. Don’t overmix or the texture gets weird.
Pour the batter into the prepared loaf pan.
Bake for 50–60 minutes, or until a toothpick poked into the center comes out with just a crumb or two.
Let it cool in the pan for 10 minutes, then turn it out onto a wire rack. Try to wait at least another 10 before slicing. Try.
