1-Preheat the oven: Preheat the oven to 350°F (177°C) and grease a baking dish to get everything ready for baking.

2-Prepare the berry mixture: In a large bowl, gently fold the berries with 1/2 cup granulated sugar, 2 tablespoons cornstarch, 1 teaspoon lemon juice, and 1/2 teaspoon pure vanilla extract. Then spread the berry mixture evenly in the prepared pan.

3-Make the biscuit dough: In another bowl, whisk together 1 and 1/2 cups all-purpose flour, 1/3 cup granulated sugar, 1 and 1/2 teaspoons baking powder, and 1/4 teaspoon salt. Cut in 6 tablespoons cold unsalted butter until the mixture resembles coarse crumbs, then slowly mix in 1/2 cup cold buttermilk until combined.

4-Assemble the cobbler: Flatten the dough into sections by hand and place over the berry layer, covering most berries but keeping an uneven, rustic look for that homemade charm.

5>Add finishing touches: Brush the biscuit dough with 1 tablespoon buttermilk and sprinkle coarse sugar on top to create a shiny, crunchy crust that adds extra appeal.

6-Bake and serve: Bake for 45-55 minutes or until the biscuits are golden brown and cooked through. Let it cool for 5 minutes before serving, and enjoy it warm with vanilla ice cream or whipped cream for the best flavor.
