Prepare the Peaches: Start by cleaning and slicing 8 large peaches. In a large bowl, mix the peach slices with ½ cup sugar, ½ cup brown sugar, 1 tsp vanilla extract, ½ tsp almond extract, 2 tsp cinnamon, ½ tsp nutmeg, 4 tsp cornstarch, 2 tsp cream of tartar, 4 tbsp melted unsalted butter, 2 tbsp water, and 1 tsp lemon juice. Stir until the peaches are fully coated.
Bake the Peaches: Preheat your oven to 350°F (175°C). Pour the peach mixture into a greased baking dish and cover with foil. Bake for 20 minutes to soften the peaches.
Check the Juices: After 20 minutes, remove the peaches from the oven. Assess whether the peaches have released too much moisture. If so, use a turkey baster to carefully remove the excess juice to avoid a soupy cobbler.
Prepare the Cobbler Topping: While the peaches bake, mix 2 cups flour, ½ cup sugar, ½ cup brown sugar, 2 tsp baking powder, 1 tsp cinnamon, and ½ tsp salt in a large bowl. Add 1 stick of softened unsalted butter, and blend until the mixture is crumbly. Slowly stir in ½ cup hot water until the dough is well combined. It should be the consistency of biscuit dough.
Add the Topping: Once the peach mixture is ready and not overly juicy, drop spoonfuls of the cobbler topping over the peaches, covering as much of the surface as possible.
Cinnamon and Sugar Topping: In a small bowl, combine 3 tbsp sugar and 1 tsp cinnamon. Sprinkle this mixture over the cobbler topping for extra sweetness and crunch.
Bake: Return the dish to the oven and bake uncovered for 35 minutes, or until the topping is golden and crispy.
Serve: Once baked, allow the cobbler to cool slightly before serving. Enjoy warm with a scoop of vanilla ice cream!
