Step 1: Prepare the Peaches

• If using fresh peaches, peel, pit, and slice them.
• In a mixing bowl, combine the peaches, granulated sugar, brown sugar, cinnamon, nutmeg, lemon juice, and cornstarch. Toss well and let it sit for about 10 minutes to release the juices.

Step 2: Preheat the Oven and Prepare the Baking Dish

• Preheat your oven to 375°F (190°C).
• Pour the melted butter into the baking dish, spreading it evenly.

Step 3: Prepare the Batter

• In a separate bowl, whisk together the flour, sugar, baking powder, and salt.
• Gradually add the milk and vanilla extract, stirring until a smooth batter forms.

Step 4: Assemble the Cobbler

• Pour the batter evenly over the melted butter. Do not stir.
• Spoon the peach mixture evenly over the batter. Again, do not stir—this will create a perfect cobbler crust as it bakes.

Step 5: Bake the Cobbler

• Place the dish in the preheated oven and bake for 40-45 minutes, or until the crust is golden brown and the peaches are bubbling.
• Let it cool slightly before serving.
