- Toss the blackberries with the sugar, cornstarch, lemon juice, lemon zest, vanilla, and salt in the dish.
- Whisk the flour, sugar, baking powder, and salt. Cut in the cold butter until coarse crumbs form.
- Stir in the cold buttermilk just until a shaggy dough forms.
- Drop spoonfuls of dough over the berries, leaving small gaps, and sprinkle with sugar.
- Bake for 40 to 45 minutes, until the topping is golden and the filling bubbles in the center.
- Cool for at least 30 minutes before serving.
