Preheat oven to 350°F and butter a shallow 10-inch baking dish.

Spread pitted cherries evenly in the warm dish.

Whisk eggs and sugar until pale and slightly thick.

Whisk in flour and salt, then slowly add milk and vanilla until smooth.

Pour batter over cherries and bake for 40 to 45 minutes until just set.

Cool slightly, dust with powdered sugar, and serve warm or at room temperature.
