Preheat the oven to 350 F (176 C) and grease a 9x13 or slightly smaller baking or casserole dish with butter.
Prepare the Peach Filling. In a skillet over medium-low heat, combine peaches, peach juice, cinnamon, lemon juice, cornstarch, and brown sugar.
2 cups canned peaches (no sugar added), ¼ cup brown sugar or raw brown sugar, 1 ½ tablespoon cornstarch, 2 teaspoon lemon juice freshly squeezed, 1 teaspoon cinnamon, 1 cup peach juice from canned peaches
Stir until well combined. Simmer gently until the mixture becomes bubbly and thickens to the desired consistency. Be careful not to overcook it; you want it thick but not overly so. If needed, reduce the heat to low.
Transfer the peach filling to the prepared baking dish. Dot with 2 tablespoons of butter cubes in different places across the peach mixture. If desired, sprinkle more cinnamon on top of the peaches.
2 tablespoon butter cold or room temp
Make the Cobbler Topping. In a large bowl, mix the dry ingredients - flour, 5 tablespoons of oats, sugar, baking powder, and salt. Cut the cold butter into the flour mixture until it resembles crumbles. You can use pastry cutter or simply do it by hand. Take your time and be thorough in this step.
1 cup all purpose flour , 5 tablespoon white sugar, 1 teaspoon baking powder, ½ teaspoon salt, 6 tablespoon old fashioned rolled oats, 5 tablespoon butter cold cubes
Gradually pour in the cold cream in batches and stir gently to lightly combine the ingredients. Take care not to over-stir or rush the process. The resulting mixture will be thick and somewhat sticky due to the flour. Place the chunks of flour mixture on top of the peach filling, leaving some space between them to allow the peaches to peek through. Optionally, sprinkle the remaining oats on top of the batter for added texture and flavor.
⅓ cup heavy cream cold
Bake. Bake the peach cobbler in the preheated oven for approximately 30 minutes. Keep an eye on it until the top turns a beautiful golden brown, and the peach mixture beneath is bubbling.
Once done, remove the peach cobbler from the oven and let it cool for a few minutes before serving. Serve with vanilla ice cream or caramel sauce!
