- cooking spray
- 1 (6 ounce) container fresh blueberries
- 1 (6 ounce) container fresh blackberries
- 1/2 cup orange juice

- Preheat oven to 375 degrees F (190 degrees C). Spray an 8×8-inch baking dish with cooking spray.
- Stir blueberries, blackberries, orange juice, and 3 tablespoons white sugar together in a bowl. Allow berries to stand 20 to 30 minutes to accumulate juice.

- Spread a thin layer of batter over bottom of the prepared baking dish; top with berry mixture and juices. Spoon remaining batter over berries and spread into an even top layer; sprinkle top with white chocolate chips and brown sugar.
- Bake in the preheated oven until the cobbler is golden brown, the filling is bubbling, and the chips have melted, 30 to 35 minutes.
