Creating Southern Banana Cobbler is a straightforward process. Follow these steps to achieve delicious results:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Prepare the Bananas: In a mixing bowl, combine sliced bananas, granulated sugar, lemon juice, cinnamon, and vanilla extract. Toss gently to coat the bananas evenly.
3. Prepare the Baking Dish: Grease a 9×13-inch baking dish with butter or non-stick spray.
4. Make the Batter: In another bowl, whisk together the flour, baking powder, salt, and brown sugar. Gradually stir in the milk and melted butter until well combined.
5. Combine: Pour the batter into the prepared baking dish. Spread it evenly across the bottom.
6. Add Bananas: Spoon the banana mixture over the batter evenly, ensuring the bananas are distributed well.
7. Add Water: Pour the water gently over the entire dish. This will create a delicious sauce as it bakes.
8. Bake: Place the dish in the preheated oven and bake for 30-35 minutes, or until the top is golden brown and the cobbler is bubbly.
9. Cool: Once baked, remove from the oven and allow it to cool for a few minutes before serving. The cobbler will set as it cools.
