Creating Clean Southern Banana Cobbler can be straightforward if you follow these simple steps:

1. Preheat your oven to 350°F (175°C).
2. In a mixing bowl, combine the sliced bananas and granulated sugar. Set aside to allow the bananas to release their juices.
3. In another bowl, whisk together the melted butter, flour, baking powder, salt, milk, vanilla extract, and cinnamon (if using) until smooth.
4. Grease a 9×13-inch baking dish with butter or cooking spray.
5. Pour the batter into the prepared baking dish, spreading it evenly.
6. Spoon the banana mixture over the batter, evenly distributing it.
7. Do not stir; the bananas will sink as it bakes.
8. Bake in the preheated oven for 40-45 minutes or until the top is golden brown and a toothpick inserted in the center comes out clean.
9. Once baked, remove from the oven and let it cool for about 15 minutes before serving.
