Preheat the oven to 350°F (175°C). In a mixing bowl, combine the cherries, sugar, cornstarch, vanilla extract, and lemon juice. Mix well and set aside.

In another mixing bowl, whisk together the flour, sugar, baking powder, and salt. Add the milk and melted butter, stirring until just combined.

Pour the cherry mixture into a greased baking dish. Spoon the topping over the cherries evenly.

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

Let cool slightly before serving. Enjoy warm, optionally with vanilla ice cream.
