Preheat the Oven: Preheat your oven to 375°F (190°C). Lightly grease a 9-inch baking dish.
Make the Blueberry Filling: In a mixing bowl, toss blueberries with sugar, cornstarch, and lemon juice until evenly coated. Transfer to the prepared baking dish.
4 cups blueberries, 1/2 cup granulated sugar, 1 tbsp cornstarch, 1 tbsp lemon juice
Combine Dry Ingredients: In another bowl, whisk together flour, sugar, baking powder, and salt.
1 cup all-purpose flour, 1/3 cup granulated sugar, 1 tsp baking powder, 1/4 tsp salt
Cut in the Butter: Add cold butter pieces to the flour mixture. Use a pastry blender or your fingertips to work the butter into the flour until it resembles coarse crumbs.
4 tbsp unsalted butter
Add Milk: Stir in the milk just until the dough comes together. Do not overmix.
1/3 cup milk
Top the Berries: Drop spoonfuls of the dough over the berry mixture. It’s okay if some berries peek through.
Bake: Bake for 25-30 minutes or until the topping is golden brown and the berry filling is bubbling around the edges.
Cool and Serve: Let the cobbler rest for 10 minutes. Serve warm with a scoop of vanilla ice cream or whipped cream.
