Best Blackberry Cobbler

Directions

1. Place the blackberries in a large bowl. Combine the sugar, cornstarch and lime zest; sprinkle over berries and gently toss to coat. Pour into a greased 9-in. square baking dish.
2. In a large bowl, combine the flour, 2 tablespoons sugar, baking powder, salt and baking soda; cut in 5 tablespoons butter until crumbly. Combine sour cream and heavy cream; gradually add to crumb mixture, tossing with a fork until mixture forms a ball.
