Yes, you can bake cobbler ahead of time and store it as mentioned above. You can reheat it in the oven at 350°F for around 20 minutes, or until hot and bubbly. OR heat single portions of the cobbler in short bursts in the microwave in microwave-safe bowls. I do, however, not recommend assembling the cobbler ahead to bake later. The biscuit topping needs to be baked right away, or else it loses its fluffiness.
