1-Preheat the oven: Preheat oven to 350°F and lightly grease a 9×13-inch baking dish.

2-Prepare the peaches: Peel and slice fresh peaches, then toss with lemon juice, brown sugar, cinnamon, and nutmeg in a bowl; set aside.

3-Make the batter: Whisk flour, granulated sugar, baking powder, and salt; add milk and vanilla, stirring until smooth with a few small lumps.

4-Add the butter: Pour melted butter into the greased baking dish, ensuring it spreads evenly across the bottom.

5-Pour the batter: Gently pour the batter over the melted butter without stirring; let it sit in a layer.

6-Add the peaches: Spoon the peach mixture evenly over the batter without stirring; the batter will rise around the fruit as it bakes.

7-Bake the cobbler: Bake at 350°F for 40-50 minutes until golden brown and bubbling; avoid opening the oven early to prevent a soggy crust.

8-Cool and serve: Remove from oven and let rest at least 10 minutes for juices to thicken; serve warm.
