Learn how to make a heartwarming recipe for peach cobblers with John Barricelli.
Make the filling: Preheat oven to 350 degrees. In a large bowl, whisk together sugar and cornstarch. Add peaches and lemon juice; toss to combine. Divide filling evenly among four 8-ounce custard cups (or one 2-quart baking dish); transfer to a rimmed baking sheet.
Make the topping and bake: In a large bowl, whisk together flour, 3 tablespoons sugar, baking powder, baking soda, and salt. Using a pastry blender or your fingers, blend in butter until mixture resembles coarse meal. Add buttermilk; stir just until a dough forms. Drop dough onto peaches, using about 1/3 cup dough for each custard cup. Sprinkle dough with remaining teaspoon sugar. Bake until fruit is bubbling and biscuit topping is golden brown, 35 to 45 minutes. Let cool 15 minutes; serve warm.
