Preheat your oven to 375°F (190°C) and grease a baking dish with butter.

Toss the strawberries with sugar and lemon juice in a large bowl until they're well-coated.

Whisk the flour, baking powder, salt, and sugar in a separate bowl until combined.

Cut the cold butter into the dry ingredients using a pastry cutter or your fingers until the mixture resembles coarse crumbs.

Stir in the milk and vanilla extract gently until just combined.

Drop spoonfuls of the batter over the strawberry mixture, spreading it out as evenly as you can.

Bake for 35–40 minutes until the topping is golden brown and bubbling.
