Creating Old Fashioned Peach Cobbler is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Prepare Peaches: In a large bowl, combine the sliced peaches, 1/2 cup of sugar, cinnamon, lemon juice, cornstarch, and vanilla extract. Toss until the peaches are evenly coated.
3. Prepare Baking Dish: Pour the peach mixture into a greased 9×13-inch baking dish, spreading it out evenly.
4. Make Batter: In another bowl, whisk together the flour, remaining sugar (1/2 cup), baking powder, and salt. Gradually add the milk and melted butter, stirring until just combined.
5. Pour Batter: Carefully pour the batter over the peaches in the baking dish. Do not stir; the batter will float on top.
6. Bake: Place the dish in the preheated oven and bake for 30-35 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
7. Cool: Remove the cobbler from the oven and let it cool for about 10-15 minutes before serving.
