Instructions:

1. Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan.
2. Mix Dry Ingredients: In a medium bowl, sift together flour, baking soda, cinnamon, and salt. Set aside.
3. Prepare Wet Ingredients: In a larger bowl, cream together brown sugar and room-temperature butter until smooth. Add eggs one at a time, mixing well after each addition. Stir in sour cream, mashed bananas, and vanilla extract until well combined.
4. Combine Dry and Wet Mixtures: Gradually fold the dry ingredients into the wet mixture until just combined. Be careful not to overmix.
5. Bake: Pour the batter into the prepared loaf pan. Bake for 55-60 minutes, or until a toothpick inserted into the center comes out clean. Remove from oven and let cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
6. Prepare Salted Caramel Glaze: While the bread is cooling, make the glaze. In a small saucepan over medium heat, melt brown sugar and butter until the sugar is dissolved (about 1 minute). Remove from heat and stir in heavy cream. Add powdered sugar and kosher salt, whisking until smooth.
7. Glaze the Bread: Allow the glaze to cool for about 5 minutes, then drizzle it over the cooled banana bread.
