Preheat the oven to 350°F and generously butter a medium sized baking dish (we used this 11 x 6 inch oval dish) with softened butter.
Place the pitted cherries in the baking dish, arranging them into a single layer. Sprinkle the 2 Tablespoons granulated sugar over the cherries. Set aside.
Place all of the other ingredients in a high powered blender and blend on high speed for 2 minutes or until frothy and light.
Pour the batter over the cherries.
Bake for 40 minutes or until the clafoutis is has puffed up and is golden brown along the edges, but still wobbles a little in the middle. If your baking dish is smaller and thicker, you might need to leave it in for a few more minutes!
Allow to cool slightly before serving with powdered sugar!
