01 - Preheat the oven to 350°F. Grease and line a 9 x 5-inch loaf pan with parchment paper.
02 - In a large mixing bowl, whisk together mashed bananas, eggs, melted butter, brown sugar, granulated sugar, and vanilla extract until well combined.
03 - In a separate bowl, whisk together flour, baking soda, salt, and cinnamon.
04 - Add the dry ingredients to the wet ingredients and gently fold together until just combined—do not overmix.
05 - Fold in the chocolate chips, reserving a small handful to sprinkle on top.
06 - Pour the batter into the prepared loaf pan and smooth the top. Sprinkle reserved chocolate chips over the batter.
07 - Bake for 50–60 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
08 - Let cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
