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

Peel and slice ripe bananas into thick rounds, then sprinkle the brown sugar and cinnamon over them. Let sit for about 5 minutes.

Whisk together the flour, baking powder, and a pinch of salt in a bowl. In another bowl, mix melted butter, brown sugar, milk, and vanilla extract until smooth. Gradually combine with the dry ingredients.

Pour half of the batter into the greased baking dish, layer the caramelized bananas, and then cover with the remaining batter.

Bake for 30-35 minutes until the top is golden brown and a toothpick inserted comes out clean.

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