Preheat your oven to 350°F (175°C) and grease a loaf pan. Your future self will thank you when the bread comes out cleanly.
In a large bowl, whisk mashed bananas, eggs, melted butter, vanilla, and sugar until smooth.
Stir in flour, baking soda, and salt until just combined. Don’t over-mix; we’re aiming for tender, not tough.
Fold in optional cinnamon, chips, or nuts if you’re feeling fancy. This is where you personalize the loaf.
Pour batter into the pan and bake 50–60 minutes, or until a toothpick comes out clean. If the top is browning too fast, tent with foil after 30 minutes.
Cool in the pan for about 10 minutes, then transfer to a rack to finish cooling. Slice when cooled enough to handle—which is sooner than you think.
