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

In a bowl, mix the blueberries with sugar and set aside to release their juices.

In another bowl, whisk together flour, baking powder, and salt. Add milk and melted butter; stir until smooth.

Pour the blueberry mixture into the dish and dollop the batter on top.

Bake for 30-35 minutes or until golden brown and bubbly.

Serve warm with ice cream or whipped cream.
