Melt the butter. Add the butter to a 9 x 9-inch baking dish. Set the baking dish in the oven and preheat the oven to 350°F. Prepare the batter ingredients while the butter is melting. Once the butter is melted in the oven, after 4-6 minutes, remove the baking dish.
4 tbsp unsalted butter
Prepare the batter. Mix the flour, sugar, baking powder, and salt in a bowl. Whisk to incorporate evenly. Add the milk and vanilla extract and whisk until smooth. Pour the batter into the baking dish with the melted butter. There is no need to stir.
¾ cup all-purpose flour, 1 cup granulated sugar, 2 tsp baking powder, ½ tsp kosher salt, ⅔ cup whole milk, 1 tsp vanilla extract
Add the cherries. Sprinkle the cherries directly on top of the batter, along with any of their juices.
4 cups fresh or frozen pitted cherries
Bake and serve. Bake in the preheated 350°F oven until the cobbler is golden and set in the middle, 45-55 minutes. Once baked, remove from the oven and cool for 15 minutes before serving.
