Preheat your oven to 400°F and grease your 10-inch cast-iron skillet or baking pan using a baking spray or softened butter
Add the eggs, whole milk, vanilla, flour, cocoa powder, brown sugar, and salt in a blender and blend until smooth. Then, pour the batter into the prepared skillet.
4 large eggs, 1 cup whole milk, 2 teaspoons vanilla, ¼ cup + 3 Tablespoons all-purpose flour, 1 Tablespoon cocoa powder, ½ cup brown sugar, ¼ teaspoon salt
Arrange the figs, sliced in half, by laying them skin side down into the batter ever so gently. Then, sprinkle with demerara sugar before baking.
3 cups figs, 1 Tablespoon demerara or turbinado sugar
Bake for 25-30 minutes or until the clafoutis is puffed and a dark, golden brown on top. It may be a bit challenging to establish a cooked color as the clafoutis is chocolate - use a toothpick to test if the clafoutis is fully baked by placing it into the middle of the clafoutis. If you do not see any wet batter when removing the toothpick, you are good to go!
Once cooled, sprinkle with confectioners sugar to serve.
1 Tablespoon powdered sugar
