Steps

1. Preheat the oven to 350 degrees. Butter a loaf pan and line the bottom with parchment paper.
2. In a medium mixing bowl, stir together the flour, salt, baking powder, and baking soda.
3. In a large mixing bowl, mash the bananas with a fork or masher into large chunks (you don’t want it to be totally smooth — the banana should still have texture). You should have 2 cups.
4. Add the eggs, both sugars, the vanilla, and oil or butter, and beat until thick.
5. Fold in the dry ingredients and stir until just blended — don’t overbeat! Stir in the chocolate chips.
6. Pour the batter into the prepared pan. Bake for 1 hour, or until the loaf has risen and a knife or skewer inserted in the middle comes out clean.
7. Cool in the pan for 15 minutes. Run a knife or offset spatula along the edges and invert onto a rack or a plate. Peel off the parchment paper and invert again.
8. Eat warm or at room temperature.
