Spread the sliced bananas evenly in a greased baking dish.

Sprinkle the brown sugar, granulated sugar, and cinnamon over the bananas. Mix only enough to coat.

In a bowl, stir together the flour, baking powder, and salt.

Add the milk, melted butter, and vanilla extract. Mix until smooth.

Pour the batter over the bananas without stirring.

Bake until the top is golden brown, the edges are bubbling, and the center is set but still soft underneath.

Let the cobbler cool for 10–15 minutes before scooping it into bowls.

Serve warm with vanilla ice cream if desired.
