Preheat your oven to 375°F (190°C). Peel, pit, and slice the peaches, then toss with sugar, cinnamon, nutmeg, and lemon juice in a large bowl.

In another bowl, whisk together flour, sugar, baking powder, and salt. Cut in cold butter until the mixture resembles coarse crumbs. Stir in milk just until blended.

Grease a 9x13-inch baking dish. Pour in the peach mixture and spread evenly. Drop spoonfuls of dough over the peaches.

Bake for 40–45 minutes until the topping is golden brown and the peach filling is bubbling.

Let cool for a few minutes before serving warm, optionally with vanilla ice cream or whipped cream.
