Preheat the oven to 180°C (350°F).
Slice the peaches and place them in a baking dish.
Sprinkle sugar and cinnamon over the peaches.
In a bowl, mix flour, baking powder, and salt.
Add milk and stir to form a smooth batter.
Pour melted butter evenly into the baking dish, then place the peaches on top.
Pour the batter evenly on top.
Do not stir; let it layer naturally.
Bake for 40–45 minutes, or until the top is golden brown and crisp.
Check if the top is crisp and set.
Remove from the oven and let it cool slightly.
Let it rest for 10–15 minutes to allow the cobbler to set and make slicing easier.
Serve warm.
