01 - Preheat the oven to 375°F.
02 - In a large bowl, combine strawberries, sugar, cornstarch, lemon juice, and vanilla extract. Toss gently until the strawberries are evenly coated.
03 - Pour the strawberry mixture into a 9-inch baking dish and spread into an even layer.
04 - In a separate bowl, whisk together flour, sugar, baking powder, and salt until well combined.
05 - Add cubed cold butter to the dry ingredients. Use a pastry cutter or your fingers to blend until the mixture resembles coarse crumbs with pea-sized butter pieces remaining.
06 - Stir in the milk and vanilla extract until just combined. Be careful not to overmix; a few small lumps are acceptable.
07 - Drop spoonfuls of the batter evenly over the strawberries, leaving some gaps for the fruit to show through.
08 - Bake for 35 to 40 minutes, or until the topping is golden brown and the strawberry filling is bubbling around the edges.
09 - Let the cobbler cool for at least 10 minutes before serving. Serve warm, optionally topped with vanilla ice cream or whipped cream.
