Chocolate Banana Bread for 12 Slices

Instructions:

1. Preheat your oven to 175°C. Grease your 9x5 inch loaf pan and line it with parchment paper Note: leave an overhang on the sides to lift the bread out later.
2. Mash the bananas in a large bowl until smooth. Stir in the melted butter, brown sugar, egg, and vanilla until the mixture looks glossy and well combined.
3. In a separate small bowl, whisk together the flour, baking soda, salt, and 2g of cinnamon.
4. Gently fold the flour mixture into the banana base using a spatula Note: stop as soon as you see no more white streaks.
5. Stir in the chocolate chips until just combined, making sure they're evenly distributed.
6. Pour half of the batter into the prepared loaf pan, smoothing the top with your spatula.
7. Evenly sprinkle the 16g cinnamon and 25g sugar mixture over the batter layer.
8. Top with the remaining batter. Use a knife or skewer to gently swirl the layers together in a figure eight motion until you see streaks of cinnamon.
9. Bake for 55-65 minutes until a toothpick inserted into the center comes out clean or with a few moist crumbs.
10. Let the bread cool in the pan for 10 minutes before removing it to a wire rack.
