Preheat your oven to 375°F. Grease a baking dish and add fresh blueberries. Sprinkle with ¼ cup sugar and cinnamon, stirring gently to coat the berries evenly.
In a mixing bowl, combine flour, baking powder, salt, and the remaining sugar. Stir in milk, melted butter, and vanilla extract until a smooth batter forms.
Pour the batter evenly over the blueberries in the baking dish. Do not stir—this allows the batter to rise over the fruit as it bakes.
Place the dish in the oven and bake for 40 minutes or until the top is golden brown and the fruit is bubbling. Let it cool for a few minutes before serving.
Spoon the warm cobbler onto plates and serve with a scoop of vanilla ice cream for the perfect pairing. For another comforting dessert, try this Southern Chocolate Cobbler.
