In a small bowl combine the cinnamon and sugar until fully combined.
For Banana Bread:
Preheat the oven to 350 degrees (F). Spray a 9x5 loaf pan with non-stick spray and set aside.
In a medium bowl combine the melted butter and bananas together. Mix the two together until the bananas are fully mashed and the butter is no longer hot.
Add the eggs and vanilla and beat until combined.
In a medium bowl whisk the flour, sugar, baking soda, salt, and cinnamon until there are no lumps.
Fold the dry ingredients into the wet until just combined. Fold in the chocolate chips.
Pour the batter into the prepared pan and sprinkle the top with the cinnamon-sugar mixture. Bake for 45-55 minutes or until an inserted toothpick comes out with a few moist crumbs. If the banana bread starts to get too brown you can cover it with foil for the remainder of the baking time.
Use overripe bananas. Overripe bananas are a must in banana bread. The more a banana ripens, the sweeter it becomes, adding lots of flavor to the banana bread.
Don't over-mix the batter. This is a pretty obvious one, but it can make a huge difference in the final product. Only mix until the ingredients are just combined.
Don't over-bake the banana bread. It can be really easy to bake the bread for too long, but make sure when you insert a toothpick it still has a few moist crumbs on it. When you remove the banana bread from the oven it will continue to bake from the residual heat.
