Preheat the oven to 350°F. Spray a 9X5 loaf with baking nonstick spray. Line the bottom and 2 sides with parchment paper. Spray again.
Heat the butter in the microwave until melted. Let it slightly cool for 5 minutes before using. While you wait, mash the bananas. It is easier to mash on a plate, use a fork or potato masher.
½ cup Unsalted butter, 3 Ripe bananas
In a mixing bowl, mix the butter, brown sugar, sour cream, vanilla, and eggs. Add in the mashed bananas and mix again.
¾ cup Brown sugar, ¼ cup Sour cream, 2 Large eggs, 1 teaspoon Pure vanilla extract
Add in flour, baking soda, salt, and cinnamon. Fold until mixed together. Make sure to not to over mix.
2 cups All-purpose flour, 1 teaspoon Baking soda, ½ teaspoon Salt, 1 teaspoon Ground cinnamon

In a small bowl, melt the butter. Add in sugar, brown sugar, cinnamon, and nutmeg. Mix until combined. It should be able to mix into the batter just fine. Make sure it isn't too thin.
3 tablespoon Unsalted butter, 3 tablespoon White granulated sugar, 3 tablespoon Brown sugar, 1 tablespoon Ground cinnamon, ¼ teaspoon Ground nutmeg
Pour ⅓rd of the batter into the pan. Use a 1 teaspoon to dollop the cinnamon mixture. Use ⅓rd of the cinnamon mixture. Use a butter knife to swirl it in. Repeat with the second layer by adding in another ⅓rd of the batter and ⅓rd of the cinnamon mixture.
Add the rest of the batter. Dollop the rest of cinnamon mixture on top. Use the butter knife to swirl it in.
Bake for 55-65 minutes. Bake until a toothpick inserted into the middle comes out clean.
Let it sit in the pan for 10 minutes before transferring to a cooling rack. Cool completely before cutting into it.

Flour- Make sure the flour is spooned and leveled or use a kitchen scale. Compacted flour can dry out the banana bread.

High altitude baking- Add an extra 2 tablespoon of flour.
