Preheat the oven to 350°F (175°C).

In a mixing bowl, combine the sliced strawberries, ¾ cup of sugar, cornstarch, and vanilla extract. Toss to coat the strawberries evenly.

Pour the strawberry mixture into a greased baking dish.

In another bowl, whisk together the flour, baking powder, salt, and ¼ cup of sugar.

Stir in the milk and melted butter until just combined.

Drop spoonfuls of the batter over the strawberry filling, covering as much of the filling as possible.

Bake in the preheated oven for 30-35 minutes, or until the topping is golden brown and a toothpick inserted into the topping comes out clean.

Let cool for a few minutes before serving.
