Preheat the oven to 350℉. Grease an 11 x 5-inch loaf pan with non-stick spray and line with parchment paper, letting the sides hang over.
Place the melted butter and brown sugar in a large bowl and whisk until combined. Add the mashed bananas, eggs, and vanilla and continue mixing.
Add the flour and baking soda and whisk just until no lumps remain (without overmixing). Fold in the pecans and chocolate chips until evenly distributed.
Pour the batter into the prepared pan and bake in preheated oven for 50-55 minutes or until a toothpick inserted into the center comes out clean.
Let cool for 5 minutes and then lift the loaf out of the pan using the parchment paper as handles and let cool on a wire rack for at least an hour or serve warm with butter. Enjoy!
