Ingredients
Dry Ingredients for Biscuit Dough
- 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
Biscuit Dough Fat and Liquid
- 8 tablespoons butter (cold, diced small)
- ¾ cup buttermilk (cold)
Blackberry Filling
- 24 ounces fresh blackberries (rinsed and dried, divided)
- ½ cup granulated sugar
- ¼ teaspoon kosher salt
- 1 teaspoon lemon zest
- 2 teaspoons lemon juice
Thickener
- 2 tablespoons cornstarch
- 3 tablespoons cold water
Additional
- Butter for brushing biscuits (about 1 tablespoon, melted)
Instructions
- Mix Dry Ingredients: In a large bowl, whisk together the flour, kosher salt, baking powder, baking soda, granulated sugar, and cinnamon until evenly combined to prepare the biscuit base.
- Cut in Butter: Add the cold diced butter to the flour mixture. Using two forks or a pastry cutter, cut butter into the flour until pieces are coated and about the size of peas.
- Form Dough: Pour in the cold buttermilk and fold gently until a shaggy dough forms. Take care not to overmix. Cover the dough and refrigerate until ready to use.
- Preheat Oven: Position the oven rack in the middle and preheat the oven to 375°F for baking the cobbler.
- Cook Blackberry Filling: Place half the blackberries, sugar, kosher salt, lemon zest, and lemon juice in a 10-inch cast iron skillet. Cook over medium heat until berries start to soften and release juices.
- Prepare Cornstarch Slurry: In a small bowl, combine cornstarch with cold water to form a slurry. Stir the slurry into the simmering blackberries.
- Simmer Filling: Let the blackberry mixture come to a vigorous simmer and cook for about 2 minutes until thickened.
- Finish Filling: Remove skillet from heat and stir in the remaining fresh blackberries for a balance of texture.
- Top with Biscuits: Remove biscuit dough from the refrigerator. Using a greased 1/3 cup measure, scoop dough portions evenly over the blackberry filling. Gently press to spread slightly and brush melted butter on top.
- Bake Cobbler: Place the skillet in the oven and bake for 35-38 minutes, or until the filling is thick, bubbling, and the biscuits are golden brown.
- Cool and Serve: Remove from oven and let the cobbler rest for 15 minutes before serving to allow the filling to set.
Notes
- Using a cast iron skillet helps achieve even cooking and a nice caramelized edge.
- Make sure the butter and buttermilk are cold for tender biscuits.
- Do not overmix the biscuit dough to keep it light and fluffy.
- The cornstarch slurry ensures the blackberry filling thickens properly without being runny.
- Allow the cobbler to cool after baking to set the filling and prevent burns.
- Serve with vanilla ice cream or whipped cream for extra indulgence.
