Preheat the oven to 350°F (175°C). Grease an 8-inch (20 cm) square baking dish with butter.
In a medium-sized bowl, mix together the blackberries, blueberries, sugar, cornstarch, cinnamon, nutmeg, and salt. Pour the mixture into the prepared baking dish.
In a small bowl, mix together the butter, flour, oats, and brown sugar. Sprinkle the mixture over the top of the berry mixture.
Bake for 45 minutes, or until the topping is golden brown and the berries are bubbling. Serve the cobbler warm with a scoop of ice cream or whipped cream.
