01 - Preheat the oven to 375°F.
02 - In a large bowl, combine strawberries, sugar, cornstarch, lemon juice, and vanilla extract. Toss gently until strawberries are evenly coated.
03 - Pour the strawberry mixture into a 9-inch baking dish and spread evenly.
04 - In a separate bowl, whisk together flour, sugar, baking powder, and salt until well combined.
05 - Add cubed cold butter to the flour mixture. 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. Do not overmix.
07 - Drop spoonfuls of the batter evenly over the strawberries, leaving some gaps for the fruit to peek through.
08 - Bake for 35 to 40 minutes, or until the topping is golden brown and the strawberries are bubbling around the edges.
09 - Let cool slightly for 10 to 15 minutes before serving. Top with vanilla ice cream or whipped cream if desired.
