Preheat the oven to 190°C.

In a large bowl, combine the peaches, granulated sugar, brown sugar, cinnamon, nutmeg, and lemon juice. Mix well to coat the peaches evenly and let it sit for about 10 minutes.

Pour the peach mixture into a baking dish, spreading evenly.

In a separate bowl, mix the flour, baking powder, and a pinch of salt. Add the cold butter pieces, using your fingers or a pastry cutter to mix until the mixture resembles coarse crumbs.

Stir in the granulated sugar into the flour mixture, then add the milk gradually, mixing just until a dough forms.

Drop spoonfuls of the topping over the peach filling, without spreading it out too much.

Bake in the preheated oven for 35-45 minutes, or until the topping is golden-brown and the filling is bubbly.

Let cool slightly before serving with a scoop of vanilla ice cream.
