Mixed Berry Cobbler
Nonstick cooking spray
Two 12-ounce bags frozen mixed berries, thawed (about 6 cups)
1/4 cup whole-wheat flour
1/4 cup sugar
1 orange, zest finely grated (about 2 teaspoons)
1/4 cup whole-wheat flour
1/4 cup all-purpose flour
2 tablespoons plus 1 teaspoon sugar, divided
1/2 teaspoon baking powder
1/4 teaspoon baking soda
1/4 teaspoon salt
2 tablespoons chilled unsalted butter, cut into small pieces
1/3 cup low-fat buttermilk
2 tablespoons canola oil
Instructions:
Preheat the oven to 400 degrees F. Coat an 8 by 8-inch baking dish with cooking spray.  
For the filling: In a large bowl, toss the berries with whole wheat flour, sugar and zest. Transfer the berry mixture to the baking dish and set aside.  
For the topping: In a medium bowl whisk together the whole-wheat flour, all-purpose flour, 2 tablespoons of sugar, baking powder, baking soda and salt. Cut in the butter using 2 knives or a pastry cutter until many small pebble-sized pieces are formed.  
In a small bowl or pitcher, whisk together the buttermilk and oil. Add the buttermilk-oil mixture to the dry ingredients and mix until just moistened. Do not over mix. Drop the batter onto the fruit forming 6 mounds. Sprinkle with the remaining teaspoon of sugar. Bake for 30 minutes, until fruit is bubbly and top is golden. Let stand for at least 10 minutes before serving.
