If you're making this entire menu in a single oven, we recommend baking the cobbler ahead of time — that way you can reheat it while clearing the table. Otherwise, you can just whisk together the dry ingredients beforehand, but you'll have to excuse yourself during dinner to assemble and bake the dessert.
Cobbler can be baked 6 hours ahead and cooled completely, uncovered, then chilled, covered. Before serving, let stand at room temperature 1 hour, then reheat in a preheated 350°F oven until warm, about 20 minutes.

Ingredients
Preparation
Step 1
Put oven rack in middle position and preheat oven to 425°F. Butter a 13- by 9- by 2-inch glass or ceramic baking dish (3-quart capacity).
Step 2
Whisk together cornstarch and 1 1/2 cups sugar in a large bowl, then add blackberries and peaches and toss to combine well. Transfer to baking dish and bake until just bubbling, 10 to 15 minutes.
Step 3
While fruit bakes, whisk together flour, baking powder, and salt in another large bowl, then blend in butter with your fingertips or a pastry blender until mixture resembles coarse meal. Add milk and stir just until a dough forms.
Step 4
Drop dough onto hot fruit mixture in 12 mounds (about 1/3 cup each), then sprinkle dough with remaining teaspoon sugar. Bake cobbler until top is golden, 25 to 35 minutes. Serve warm.
