Preheat your oven to 350°F (175°C).

In a medium skillet, combine sliced bananas, brown sugar, and spiced rum over medium heat. Cook until bananas are caramelized, about 5-7 minutes.

In a large mixing bowl, whisk together flour, baking powder, and salt. Cut in melted butter until mixture resembles coarse crumbs.

Gradually add milk to the dry ingredients, stirring gently until just combined.

Pour the caramelized banana mixture into an 8x8-inch baking dish and cover with dollops of the biscuit dough.

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

Serve warm, optionally with vanilla ice cream or caramel sauce.
