HOW TO MAKE BLACKBERRY COBBLER
Start by combining the blackberries, sugar, and ground cinnamon together in a saucepan over low heat. While that is just starting to warm up, combine the water and cornstarch. Gently stir that in and cook the mixture over low heat until thickened.
Next, in a medium bowl, whisk together the flour, sugar, baking powder, salt, and ground cinnamon. Now using a pastry blender cut in the cold butter until the mixture is crumbly. Then stir in the buttermilk just until the mixture is moistened.
Pour the berry mixture into a greased baking pan. Now drop the batter by rounded tablespoons onto the hot liquid. Then place in the preheated oven and bake for about 30 minutes or until golden brown and bubbly. Serve with a scoop of vanilla ice cream or with fresh whipped cream. Enjoy warm or at room temperature.
