Creating this delightful Gluten-Free Peach Cobbler can be straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Prepare Peaches: If using fresh peaches, peel and slice them. If using canned peaches, drain them thoroughly.
3. Mix Peaches and Sugar: In a large bowl, combine the sliced peaches with ½ cup of granulated sugar and optional cornstarch if using. Stir to coat and set aside.
4. Combine Dry Ingredients: In another bowl, mix the gluten-free flour, baking powder, salt, and remaining ½ cup sugar.
5. Add Wet Ingredients: Stir in the melted butter, milk, and vanilla extract to the dry mixture until fully combined.
6. Prepare Baking Dish: Pour the peach mixture into a greased 9×13-inch baking dish.
7. Add the Batter: Gently pour the batter over the peach mixture. Do not stir; the batter will rise during baking.
8. Sprinkle Cinnamon: If desired, sprinkle cinnamon over the top for added flavor.
9. Bake: Place the baking dish in the preheated oven and bake for 40-45 minutes or until the topping is golden brown and a toothpick comes out clean.
10. Cool: Once baked, remove from the oven and allow it to cool for 15 minutes before serving.
