Preheat the oven: 350°F (175°C). Grease an 8×8-inch or similar baking dish.
Prepare the filling:
In a bowl, mix blackberries, sugar, lemon juice, and cornstarch (if using).
Pour into the prepared baking dish.
Make the topping:
In a mixing bowl, whisk flour, sugar, baking powder, and salt.
Cut in cold butter using a pastry cutter or fork until mixture resembles coarse crumbs.
Stir in milk and vanilla until just combined — do not overmix.
Assemble and bake:
Drop spoonfuls of the topping over the berries; it doesn’t need to cover completely.
Bake for 40–45 minutes, until topping is golden and berries are bubbly.
Serve:
Let cool slightly before serving. Delicious with vanilla ice cream or whipped cream.
💡 Tips:
For extra flavor, sprinkle a little cinnamon or nutmeg into the topping.
If using frozen berries, you can add a couple more tablespoons of sugar to balance the tartness.
A drizzle of heavy cream over the topping before baking makes it slightly richer and golden.
If you like, I can also give you a “grandma’s secret” version where the topping is extra crispy on the outside but melt-in-your-mouth soft inside — it makes the blackberry cobbler unforgettable. Do you want me to share that?
