Preheat your oven to 350°F (175°C). Lightly grease a 9x5-inch loaf pan or line it with parchment paper for effortless removal.
In a large mixing bowl, mash your overripe bananas with a fork until smooth with a few small lumps remaining.
Add the eggs to the mashed bananas and whisk until well combined. Stir in the sugar until dissolved.
Gradually fold in the flour until just incorporated. Be careful not to overmix—stop when you no longer see dry flour.
Pour the batter into your prepared loaf pan and smooth the top with a spatula.
Bake in the preheated oven for 50-55 minutes, or until a toothpick inserted in the center comes out clean with a few moist crumbs. If the top is browning too quickly, loosely cover with aluminum foil after 30 minutes.
Allow your banana bread to cool in the pan for 10-15 minutes before transferring to a wire rack to cool completely.
