Preheat the oven to 375°F (190°C). Grease a 9×9-inch baking dish.
In a bowl, combine cherries, 3/4 cup sugar, lemon juice, cornstarch, and 1 tsp vanilla extract. Stir to coat cherries evenly.
Pour the cherry mixture into the prepared baking dish, spreading evenly.
In another bowl, mix flour, baking powder, 1/2 cup sugar, and salt. Stir in milk, melted butter, and 1 tsp vanilla extract until smooth.
Pour the topping batter over the cherry filling, spreading it evenly.
Bake for 45-50 minutes until the topping is golden and the filling is bubbly around the edges.
Let it cool for a few minutes before serving warm with ice cream or whipped cream if desired.
Notes
Customize this cobbler by adding a few blueberries or raspberries for a mixed berry twist, or a pinch of cinnamon or nutmeg to the topping for extra warmth.
