Preheat your oven to 350°F (175°C) and grease your loaf pan.

Mash 3-4 ripe bananas until mostly smooth.

Combine ½ cup melted unsalted butter with ½ cup granulated sugar and ½ cup brown sugar.

Beat in 2 large eggs and 1 teaspoon of vanilla extract into the butter-sugar mixture.

Mix in the mashed bananas until combined.

In a separate bowl, whisk together 2 cups of flour, 1 teaspoon baking soda, ½ teaspoon salt, and 2 teaspoons cinnamon.

Fold the dry ingredients into the banana mixture just until combined.

Pour the batter into the greased loaf pan and sprinkle with cinnamon-sugar mixture.

Bake for 50-60 minutes until a toothpick comes out clean.

Let the bread cool in the pan for 10 minutes before transferring to a wire rack.
