Creating Old School Easy Brown Sugar Peach Cobbler is straightforward when you follow these essential steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Prepare Peaches: If using fresh peaches, slice them and place them in a bowl. If using frozen, let them thaw slightly.
3. Mix Brown Sugar: Add brown sugar to the peaches and gently toss to coat. This helps to enhance their natural sweetness.
4. Combine Dry Ingredients: In a medium bowl, whisk together flour, granulated sugar, baking powder, and salt.
5. Add Wet Ingredients: Pour in the milk, melted butter, and vanilla extract. Mix until just combined.
6. Pour Mixture: Pour the batter into a greased 9×13-inch baking dish.
7. Add Peaches: Spoon the peach mixture evenly over the top of the batter. Do not stir; the batter will rise around the peaches as it bakes.
8. Sprinkle with Cinnamon: If desired, sprinkle a little cinnamon on top for extra flavor.
9. Bake: Place in the preheated oven and bake for 30-40 minutes, or until the cobbler is golden brown and a toothpick inserted into the batter comes out clean.
10. Cool Slightly: Allow it to cool for a few minutes before serving.

These steps will guide you to create a beautiful cobbler that will wow your family and friends.
