Start by preheating your oven to 350°F (175°C). Grease your loaf pan with butter or line it with parchment paper for easy removal.
In a large mixing bowl, whisk together the flour, baking soda, and salt. This step ensures even distribution of the leavening agent and salt throughout your bread.
In another bowl, mash the very ripe bananas with a fork until smooth. The riper the bananas, the sweeter your bread will be!
Add the melted butter and sugar to the mashed bananas. Stir until well mixed, then add the eggs and vanilla extract. Mix until fully combined.
Pour the banana mixture into the dry ingredients. Gently fold the mixture using a rubber spatula until just combined. Be careful not to overmix; a few lumps are okay!
In a small bowl, combine the tablespoon of ground cinnamon with the two tablespoons of sugar. Set aside.
Pour the batter into your prepared loaf pan. Sprinkle the cinnamon sugar mixture generously over the top. This will create a delightful crunchy layer as it bakes!
Place the loaf pan in the preheated oven and bake for 60 minutes, or until a toothpick inserted into the center comes out clean. If the top starts to brown too quickly, cover it loosely with aluminum foil.
Once baked, remove the bread from the oven and let it cool in the pan for about 10 minutes. Then transfer it to a cooling rack to cool completely. Slice and enjoy your Cinnamon Topped Banana Bread warm or at room temperature!
