Ingredients
Scale
- 1 ½ cup all-purpose flour
- ¾ teaspoon kosher salt
- 1 ½ teaspoon baking powder
- ¼ teaspoon baking soda
- 3 tablespoons granulated sugar
- ¼ teaspoon ground cinnamon
- 8 tablespoons butter cold, diced small
- ¾ cup buttermilk cold
- 24 ounces fresh blackberries rinsed and dried, divided
- ½ cup granulated sugar
- ¼ teaspoon kosher salt
- 1 teaspoon lemon zest
- 2 teaspoons lemon juice
- 2 tablespoons cornstarch
- 3 tablespoons cold water
Instructions
- In a large bowl, whisk together the flour, salt, baking powder, baking soda, sugar, and cinnamon until evenly mixed.
- Add the cold butter and cut it into the flour using two forks or a pastry cutter until the butter resembles pea-sized pieces.
- Gently fold in the buttermilk until a shaggy dough forms, then cover and refrigerate until ready for use.
- Preheat your oven to 375°F with the oven rack in the middle position.
- In a 10-inch cast iron skillet, combine half of the blackberries, sugar, salt, lemon zest, and juice, cooking over medium heat.
- Make a slurry by mixing cornstarch and water in a small bowl; add this to the skillet once the berries start to soften. Let it simmer for about 2 minutes.
- Remove the skillet from heat and stir in the remaining blackberries.
- Retrieve the biscuit dough from the refrigerator. Use a greased 1/3 measuring cup to scoop and evenly distribute the dough on top of the blackberries, gently pressing down.
- Brush melted butter over the biscuit tops and place the skillet in the oven.
- Bake for 35-38 minutes until the filling bubbles and the biscuits turn golden brown. Let sit for 15 minutes before serving.
Notes
For added flavor, try incorporating other berries such as raspberries or blueberries.
Serve warm with a scoop of vanilla ice cream for a delicious contrast.
Make ahead by preparing the filling and dough separately, then assemble and bake before serving.
