Preheat oven to 350 degrees F. Rub a 10" cast-iron skillet with butter and place in oven to preheat.
To a blender or food processor, add milk, sugar, eggs, vanilla, salt and flour. Blend on high 1 minute, until smooth.
Using oven mitts, carefully remove hot pan from oven and pour in batter. Scatter blackberries, raspberries and strawberries evenly over batter. Bake 40 to 45 minutes, until top of clafoutis is puffed and golden, and a toothpick inserted into center comes out clean. Let clafoutis cool in skillet. Dust with confectioners' sugar to serve.
Tip: When testing doneness, be sure not to insert your toothpick into a berry. Serve for dessert with a dollop of whipped cream, or for breakfast with a dollop of yogurt.
