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

In a large mixing 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, whole milk, and additional granulated sugar until just combined.

Pour the batter into the greased baking dish and gently spoon the banana mixture over the batter.

Bake for 45-50 minutes until golden brown and bubbly.

Let cool for about 10 minutes before serving with ice cream or whipped cream.
