If peaches are extra juicy, add an additional tablespoon of flour or cornstarch to the fruit mixture to prevent a runny filling. Use room-temperature butter for the crumble to achieve a perfect crumbly texture. Tent with foil if topping browns too quickly. Let cobbler rest after baking to thicken juices. Frozen peaches can be used if thawed and drained. For gluten-free, substitute almond flour for regular flour. For dairy-free, use coconut oil or vegan butter.
