Ingredients
Blackberry Filling
-
4 cups fresh blackberries (or frozen, thawed and drained)
-
¾ cup granulated sugar
-
1 tablespoon lemon juice
-
1 teaspoon vanilla extract
Cobbler Batter
-
1 cup all-purpose flour
-
1 cup granulated sugar
-
1 tablespoon baking powder
-
¼ teaspoon salt
-
1 cup milk
-
½ cup unsalted butter
Instructions
Preheat oven to 350°F (175°C). Place the butter in a 9×13-inch baking dish or cast-iron skillet and set it in the oven until melted. Carefully remove and set aside.
In a bowl, gently toss blackberries with sugar, lemon juice, and vanilla extract. Set aside so the berries release their natural juices.
In a separate bowl, whisk together flour, sugar, baking powder, and salt. Slowly add milk, whisking until a smooth, pourable batter forms.
Pour the batter evenly over the melted butter in the baking dish. Do not stir. Spoon the blackberry mixture evenly over the batter, including the juices. Again, do not stir—the layers will create the cobbler texture as it bakes.
Bake uncovered for 45–50 minutes, or until the top is golden brown and the blackberry filling is bubbling around the edges. Remove from oven and let cool slightly before serving.
Notes
-
Do not stir the layers—this is key to classic cobbler texture.
-
Use ripe, flavorful blackberries for best results.
-
Frozen berries should be thawed and drained to avoid excess liquid.
-
Cobbler thickens as it cools, so allow resting time.
