Preheat your oven to 350°F (175°C). Grease a 9x5-inch loaf pan or line it with parchment paper.
Combine Wet Ingredients:
In a large bowl, whisk together the melted butter, sugar, eggs, vanilla extract, and milk. Stir in the mashed bananas until well combined.
Combine Dry Ingredients:
In a separate bowl, whisk together the flour, baking soda, baking powder, and salt.
Mix the Batter:
Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix.
Pour into Pan:
Pour the batter into the prepared loaf pan and smooth the top with a spatula.
Bake:
Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean. Allow the bread to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
Add the Salted Caramel Topping:
Drizzle the Caramel:
Once the banana bread has cooled, drizzle the caramel sauce over the top.
Sprinkle with Salt:
Sprinkle the flaky sea salt evenly over the caramel for a salted caramel finish.
Serve:
Slice and Serve:
Slice the banana bread and serve as a dessert, snack, or breakfast treat.
