Preheat the oven to 350°F (175°C) and grease a baking dish with butter.
Whisk together the milk, eggs, sugar, vanilla extract, and salt until well combined.
Add the flour gradually, whisking until smooth and lump-free.
Pour half of the batter into the prepared baking dish.
Distribute the pitted cherries evenly over the batter.
Pour the remaining batter over the cherries, covering them completely.
Bake in the preheated oven for 40-45 minutes, or until the top is golden and a toothpick inserted comes out clean.
Cool slightly before dusting with powdered sugar and serving warm.
