Preheat oven to 350°F (175°C). Grease a 9×5-inch loaf pan.
In a medium bowl, whisk together flour, baking soda, salt, and cinnamon.
In a large bowl, cream together butter and sugar until light and fluffy.
Beat in eggs, one at a time, then stir in vanilla extract.
Mix in mashed bananas and sour cream until well combined.
In a separate bowl, beat cream cheese until smooth.
Pour half of the banana batter into the prepared loaf pan. Spread the cream cheese over the batter. Top with remaining banana batter.
Bake for 60-70 minutes, or until a toothpick inserted into the center comes out clean.
Allow the bread to cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
