Preheat oven to 350°F.
Butter a 9×5-inch loaf pan.
Mix flour, sugar, baking soda, cinnamon, pecans, salt, and nutmeg in a large basin.
Inside another bowl, mix eggs, buttermilk, brown sugar, vanilla, and buttermilk. Add bananas to the mixture.
Blend the banana-flour mixture well. Leave lumps in the mixture, but don't over-mix.
Put the batter into the loaf pan. Bake for an hour, or until golden. The bread should rest in the pan for 10 minutes before being moved to a cooling rack. Cook and serve in bite-sized pieces.
