Mash the bananas with a fork in a large bowl.

Add the eggs, sugar, oil, buttermilk, and vanilla.

Mix the wet ingredients really well.

Add the flour, baking soda, and salt.

Mix until just combined. You do not want to over-mix this batter.

Fold in the nuts or chocolate chips.

Pour the batter into a loaf pan coated with cooking spray. This recipe makes two loaves.

Bake the bread in a preheated 350-degree oven for about an hour, or when a tester comes out clean.
