Preheat your oven to 350°F (175°C) and grease an 8½ x 4½ inch loaf pan.

In a mixing bowl, combine 1 ½ cups all-purpose flour, 1 teaspoon baking soda, and ¼ teaspoon salt.

Mash 3 to 4 ripe bananas in a large bowl until mostly smooth, leaving small chunks for texture.

Add ¾ cup granulated sugar, 2 large eggs, 6 tablespoons melted butter, ⅓ cup sour cream, and 1 teaspoon vanilla extract to the mashed bananas and combine.

Fold the dry ingredients into the wet ones until just combined, being careful not to overmix.

Pour the batter into the greased loaf pan and smooth the top with a spatula.

Bake for 50 to 60 minutes or until the top is golden brown and a toothpick comes out clean.

Let the banana bread cool in the pan for 15 to 20 minutes before transferring to a wire rack to cool completely.
