Preheat the Oven:

• Preheat your oven to 375°F (190°C).

Prepare the Filling:

• In a large bowl, mix the sliced peaches with 1/2 cup of granulated sugar, lemon juice, cinnamon, and cornstarch (if using). Toss until the peaches are well coated. Pour this mixture into a greased 9×13-inch baking dish.

Make the Topping:

• In another bowl, combine 1 cup of all-purpose flour, 1 tablespoon of baking powder, 1/2 teaspoon of salt, and 1/4 cup of granulated sugar. Stir until well mixed.
• Add 1/4 cup of melted unsalted butter and 1/2 cup of milk to the dry ingredients. Mix until just combined; do not overmix.

Assemble the Cobbler:

• Pour the topping batter over the peach filling in the baking dish. You can spread it out gently, but it’s okay if some of the peach filling peeks through.

Bake:

• Bake in the preheated oven for 30-35 minutes, or until the topping is golden brown and the filling is bubbling around the edges.

Cool and Serve:

• Remove from the oven and allow the cobbler to cool for about 10 minutes before serving. This dessert is best enjoyed warm, preferably with a scoop of vanilla ice cream or a dollop of whipped cream.
