Prepare the Filling:
Preheat your oven to 350°F (175°C). Grease a 9x13 inch baking dish.
In a large mixing bowl, gently toss the blackberries with the granulated sugar, lemon juice, and cornstarch until well combined.
Spread the blackberry mixture evenly in the prepared baking dish.
Prepare the Topping:
In another mixing bowl, whisk together the flour, granulated sugar, baking powder, and salt.
Stir in the melted butter, milk, and vanilla extract until the batter is smooth and well combined.
Assemble and Bake:
Pour the batter evenly over the blackberry mixture in the baking dish, spreading it gently with a spatula if needed to cover most of the berries.
Bake in the preheated oven for 45-50 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Serve:
Allow the cobbler to cool slightly before serving. Enjoy it warm, topped with a scoop of vanilla ice cream or a dollop of whipped cream if desired.
