Preheat your oven to 350°F (175°C) and grease a medium-sized baking dish with butter or non-stick spray.

In a large mixing bowl, mash or slice the ripe bananas until smooth or slightly chunky. Stir in granulated sugar, ground cinnamon, and a pinch of salt, mixing until well combined.

In a separate bowl, whisk together all-purpose flour, baking powder, and salt. Cut in unsalted butter until the mixture resembles coarse crumbs.

Pour the banana mixture into your greased baking dish, spread evenly, and drop spoonfuls of the biscuit dough over the banana layer.

Bake for about 35-40 minutes until the topping is golden brown and a toothpick inserted in the center comes out clean.

Remove from oven, cool for a few minutes, and serve warm with whipped cream or vanilla ice cream.
