Preheat your oven to 350°F (175°C). Grease or line a 9x5-inch loaf pan with parchment paper.
In a large bowl, whisk together the mashed bananas, melted butter, sugar, eggs, and vanilla until smooth.
Stir in the flour, baking soda, and salt until just combined. Avoid overmixing.
Fold in the chopped Oreo cookies.
Pour the batter into the prepared loaf pan and sprinkle additional Oreo pieces on top.
Bake for 55–65 minutes, or until a toothpick inserted into the center comes out mostly clean with a few moist crumbs.
Let the loaf cool in the pan for 10–15 minutes before transferring it to a wire rack to cool completely.
