Ingredients
Scale
- 3–4 very ripe bananas (heavily spotted or brown), mashed (about 1½ cups)

- ¼ cup sour cream or Greek yogurt
- For Cinnamon Swirl:

Instructions
- Preheat oven to 350°F (175°C). Grease a 9×5-inch loaf pan and line with parchment paper, leaving overhanging edges.
- In a small bowl, mix together granulated sugar and 1 tablespoon cinnamon for the swirl. Set aside.
- In a large bowl, mash bananas until mostly smooth (a few lumps are fine).
- Whisk melted butter into mashed bananas, then add brown sugar, eggs, vanilla, and sour cream until well combined.
- In a separate bowl, whisk together flour, baking soda, salt, and ¼ teaspoon cinnamon.
- Gently fold dry ingredients into wet ingredients until just combined. Don’t overmix.
- Pour half the batter into prepared pan and spread evenly.
- Sprinkle half the cinnamon sugar mixture over the batter.
- Add remaining batter and spread gently, then top with remaining cinnamon sugar.
- Use a knife to make 2-3 gentle swirls through the batter. Don’t over-swirl.
- Bake for 55-65 minutes, until golden brown and a toothpick inserted in center comes out with a few moist crumbs.
- Cool in pan for 15 minutes, then turn out onto wire rack to cool completely before slicing.
