Set your oven to 220°C if using a light baking dish or 200°C for glass or dark pans.

Pop the peach slices, sugars (light brown and granulated), cinnamon, nutmeg, lemon juice, and cornstarch into a big bowl. Give them a good toss until the peaches are fully coated.
03 -
Grab a 2-litre dish and scrape in the peach mix. Let that bake in the center for around 10 minutes.
04 -
In another big bowl, toss in flour, granulated sugar, brown sugar, baking powder, and salt. Mix in the cold butter with your fingers or a pastry blender till it looks crumbly. Add boiling water and stir just until it comes together.
05 -
Take peaches out of the oven. Drop clumps of the topping on top of the hot fruit.
06 -
Sprinkle all the extra sugar evenly onto the cobbler.
07 -
Put the dish on a baking tray to catch spills. Let it bake until the top turns golden and isn’t doughy—should take about 30 minutes.

Let it cool a bit first, then dig in while it’s still warm. If you want, scoop on some ice cream.
