Ingredients

For the Blackberry Filling:

• 6 cups (about 900g) fresh or frozen blackberries (if frozen, do not thaw)

• ¾ cup (150g) granulated sugar (adjust to taste based on berry sweetness)

• 2 tbsp cornstarch or all-purpose flour

• 1 tbsp lemon juice

• 1 tsp lemon zest (optional, but brightens flavor)

• ½ tsp ground cinnamon (optional)

• Pinch of salt

For the Cobbler Topping:

• 1½ cups (190g) all-purpose flour

• ½ cup (100g) granulated sugar

• 1½ tsp baking powder

• ¼ tsp baking soda

• ¼ tsp salt

• 6 tbsp (85g) cold unsalted butter, cubed

• ¾ cup (180ml) buttermilk (or ¾ cup milk + 1 tsp vinegar, left for 5 minutes)

• 1 tsp vanilla extract

• Coarse sugar for sprinkling (optional)

Instructions

1. Prepare the Filling:

Preheat oven to 375°F (190°C). In a large bowl, gently toss blackberries with sugar, cornstarch, lemon juice, lemon zest, cinnamon, and salt until evenly coated. Pour into a 9×9-inch or 2-quart baking dish. Set aside.

2. Make the Topping:

In a medium bowl, whisk together flour, sugar, baking powder, baking soda, and salt. Cut in cold butter using a pastry cutter, fork, or your fingers until the mixture resembles coarse crumbs. Stir in buttermilk and vanilla just until a soft, shaggy dough forms—do not overmix.

3. Assemble:

Drop spoonfuls of dough (about 8–10 portions) evenly over the blackberry filling. Sprinkle the top with coarse sugar if desired.

4. Bake:

Place the baking dish on a baking sheet (to catch any bubble-overs). Bake for 40–45 minutes, until the topping is golden brown and the filling is thick and bubbling vigorously around the edges.

5. Cool & Serve:

Let cobbler cool for at least 20–30 minutes before serving—this allows the filling to set. Serve warm with vanilla ice cream, whipped cream, or a drizzle of heavy cream.

Tips for Perfect Cobbler

• Berry Sweetness: Taste a berry before mixing. If they’re tart, add up to an extra ¼ cup sugar.

• Frozen Berries: Use straight from frozen to avoid excess juice. You may need to bake 5–10 minutes longer.

• Thickener: Cornstarch gives a clearer, glossier filling; flour yields a more rustic, opaque result.

• Don’t Overmix Topping: A lumpy dough ensures a tender, flaky biscuit top.

• Buttermilk Substitute: Mix ¾ cup milk with 2 tsp lemon juice or vinegar; let sit 5 minutes before using.

Variations

• Mixed Berry Cobbler: Use a blend of blackberries, raspberries, and blueberries.

• Peach-Blackberry Cobbler: Add 2 cups sliced peaches to the berries.

• Lemon-Thyme: Add 1 tsp fresh thyme leaves to the filling for a herbal note.

• Gluten-Free: Use a 1:1 gluten-free flour blend and ensure cornstarch is GF.

• Vegan: Use plant-based butter and a buttermilk alternative (like almond milk + vinegar).

Storage & Reheating

• Store covered at room temperature up to 1 day, or refrigerate up to 3 days.

• Reheat in a 300°F (150°C) oven until warm, or microwave single servings.
