Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish.

In a large bowl, combine sliced ripe bananas, granulated sugar, melted butter, vanilla extract, ground cinnamon, and salt. Let sit for 5-10 minutes.

In another bowl, whisk together self-rising flour, milk, and additional sugar until just combined.

Pour the prepared batter into the greased baking dish. Dollop the banana mixture on top.

Bake for 45-50 minutes until golden-brown. To check for doneness, ensure the center feels set.

Let the cobbler cool for about 10 minutes before serving.
