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.
Cooks' note:
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.
