Preheat the oven to 350°F (175°C). Grease a 9-inch pie dish or baking pan with butter.

Spread the pitted cherries evenly over the bottom of the prepared baking dish.

In a mixing bowl, whisk together the flour, sugar, and salt.

In another bowl, beat the eggs, then add the milk, heavy cream, and vanilla extract. Mix well.

Gradually add the dry ingredients to the wet ingredients, whisking until smooth and lump-free.

Pour the batter over the cherries in the baking dish.

Bake for 35-40 minutes, or until the clafoutis is puffed and golden brown.

Let it cool slightly, then dust with powdered sugar before serving.
