1. Make filling: Toss all filling ingredients together in a 9-inch glass or ceramic pie plate and let stand until juicy, about 30 minutes.
2. Preheat oven to 400 degrees F.
3. Make topping: Sift together flour, baking powder and soda, salt, and 1 teaspoon sugar in a bowl. Blend in butter with your fingertips or a pastry blender until mixture resembles coarse meal. Stir in buttermilk with a fork just until combined (do not overmix).
4. Drop rounded tablespoons of dough over filling, leaving spaces in between to allow topping to expand. Sprinkle with remaining 2 teaspoons sugar.
5. Bake cobbler in middle of oven until fruit is tender and topping is golden, about 30 minutes. Cool slightly, about 15 minutes, and serve warm.
