01 - Preheat the oven to 375°F.
02 - Combine strawberries, sugar, cornstarch, lemon juice, and vanilla extract in a large bowl. 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 - Whisk together flour, sugar, baking powder, and salt in a separate bowl.
05 - Add cubed butter to the dry ingredients. Use a pastry cutter or your fingers to blend until the mixture resembles coarse crumbs.
06 - Stir in the milk and vanilla extract until just combined. Be careful not to overmix.
07 - Drop spoonfuls of the batter evenly over the strawberries, leaving gaps for the fruit to peek through.
08 - Bake for 35-40 minutes until the topping is golden brown and the strawberry filling is bubbling.
09 - Let cool slightly before serving. Add vanilla ice cream or whipped cream if desired.
