Preheat oven to 400°F. Lightly butter a 9-inch (23 cm) square pan or similar 2-quart (1.92 L) baking dish. Make the filling: In a large bowl, gently toss blackberries with 2/3 cup (160 ml) sugar, lemon juice, lemon zest, cornstarch, vanilla, and a pinch of salt until evenly coated. Spread the mixture into the prepared baking dish. Make the biscuit topping: In a medium bowl, whisk flour, 3 tablespoons (45 ml) sugar, baking powder, baking soda, and 1/2 teaspoon (2.5 ml) salt. Cut in the cold butter with a pastry cutter or your fingertips until the mixture resembles coarse crumbs with pea-sized bits of butter. Pour in the cold buttermilk and stir just until a shaggy dough forms (do not overmix). Using a spoon or scoop, drop 8–10 mounds of dough evenly over the berries, leaving small gaps for steam to escape. Brush the tops lightly with 1 tablespoon (15 ml) buttermilk and sprinkle with coarse sugar, if using. Bake 35–40 minutes, until the biscuits are golden brown and the fruit is bubbling thickly around the edges. If the tops brown too quickly, tent loosely with foil for the last 10 minutes. Cool 15 minutes to set the juices. Serve warm, ideally with vanilla ice cream or lightly sweetened whipped cream.
