Prep the Peaches
- Blanch for Easy Peeling: Bring a pot of water to a boil. Score a small X on the bottom of each peach and drop into boiling water for 30 seconds. Transfer immediately to ice water. The skins slip off effortlessly with your fingers. Pit each peach and slice into half-inch wedges. If you prefer a more rustic cobbler, skip the blanching and leave the skins on.

Make the Filling
- Toss and Rest: In a large glass bowl, combine the sliced peaches, both sugars, cornstarch, lemon juice, cinnamon, nutmeg, and vanilla. Toss gently until every piece is evenly coated. Let rest for 10 minutes while the oven preheats. The sugar draws juice from the peaches which will combine with the cornstarch to form the glossy sauce.

Preheat the Pan
- Hot Pan Is the Secret: Place the empty baking dish or cast iron skillet in the oven. Preheat to 375°F (190°C) with the pan inside for 10 to 15 minutes. The pan must be genuinely hot before the batter touches it to create a crispy base.

Make the Biscuit Topping
- Cold Butter, Do Not Overwork: Whisk together flour, both sugars, baking powder, and salt. Add the cold butter cubes and use a spoon or two forks to cut the butter into the flour until the mixture looks like coarse breadcrumbs with some pea-sized pieces still visible. Stir in the milk and vanilla until a soft, shaggy dough just comes together. Stop mixing the moment no dry flour remains. Overworking makes the topping tough instead of tender.

Assemble
- Pour Filling, Dollop Topping With Gaps: Carefully remove the hot pan from the oven. Pour the peach filling in and spread evenly. Drop large spoonfuls of topping over the peaches, leaving deliberate gaps between each dollop so steam can escape upward and the underside of the topping stays crispy. About one-third of the filling should still be visible through the gaps. Sprinkle the cinnamon-sugar mixture evenly over the biscuit dollops.

Bake Until the Filling Bubbles
- Watch the Center: Bake at 375°F for 40 to 48 minutes until the topping is deep golden brown and the filling is bubbling visibly in the center of the cobbler, not just around the edges. If the topping browns too quickly before the center bubbles, lay a piece of foil loosely over the top and continue baking.

Rest and Serve
- 10 Minutes, Then Ice Cream: Let the cobbler rest for 10 minutes after coming out of the oven. The filling continues thickening as it cools slightly. Spoon warm portions into bowls and top generously with vanilla ice cream. Serve immediately.

Notes
- Hot pan technique. Preheat the empty baking dish or skillet in the oven before adding filling and topping. This creates a crispy base layer before peach juice can soak in.
- Leave steam gaps. Always leave spaces between topping dollops. These gaps let steam escape upward rather than condensing back into the batter and making the underside soggy.
- The filling must bubble in the center. Cornstarch only fully activates at boiling temperature. Bubbling in the center confirms the filling is thick and will set properly as it cools.
- Fresh peaches: ripe but firm. Very soft, overripe peaches contain less natural pectin and produce a thinner filling. If peaches are very soft, add an extra half tablespoon of cornstarch.
- Frozen peaches: do NOT thaw. Use straight from frozen. Add 1 extra tablespoon of cornstarch and add 10 extra minutes to the baking time.
- Canned peaches in juice: Drain well. Reduce sugar by 2 tablespoons.
- Canned peaches in syrup: Drain very well. Reduce sugar by 3 to 4 tablespoons.
- Buttermilk topping: Substituting buttermilk for regular milk produces a more tender biscuit. No buttermilk: add 1 tablespoon of lemon juice to half a cup of regular milk and let sit 5 minutes.
- Taste peaches before adding sugar. August peaches can be very sweet. Reduce sugar if peaches already taste sweet to avoid an overly sugary filling.
- Storage: Room temperature up to 2 days. Refrigerator up to 4 days. Reheat in a 325°F oven for 10 to 12 minutes. Topping softens over time but flavor stays excellent.
- UK/Australia notes: "All-purpose flour" equals plain flour. "Baking powder" is the same term. "Cornstarch" equals cornflour. "Vanilla ice cream" is the same globally.
- Nutrition values are estimates and vary based on peach sweetness, exact sugar quantities, and serving size.
