Preheat the oven to 180ºC (350ºF). Place the milk, flour, granulated sugar, eggs, vanilla, and salt in a food processor or an electric blender and whirl until smooth – 5 to 10 seconds.
Arrange the cherries in the bottom of a buttered 22.5 cm (9 in) glass pie plate. Pour the batter evenly over the cherries.
Bake, uncovered, for 45 to 50 minutes or until puffed, lightly browned, and set. Let cherry clafouti cool for 15 minutes, then dust with the confectioners sugar.
