Preheat the oven to 375°F. Rinse, pit, and evenly slice the peaches (no thicker than 1/2 inch).
02 -
Add the sliced peaches, brown sugar, cornstarch, vanilla extract, cinnamon, and lemon juice to a 9x13-inch casserole dish or a 12-inch cast iron skillet. Toss until evenly combined.
03 -
In a mixing bowl, combine the flour, granulated sugar, baking powder, salt, and cinnamon.
04 -
Add the cold, cubed butter to the dry mixture. Using a pastry cutter, two forks, or your fingertips, work the butter into the flour until the mixture resembles coarse crumbs, with butter pieces about the size of small peas.
05 -
Pour the cold milk into the dry mixture and stir gently until the dough just comes together. The dough will be shaggy and lumpy. Do not overmix.
06 -
Spoon the biscuit dough over the peach filling. Leave some open spaces to allow the juices to bubble through.
07 -
Bake at 375°F for 45-50 minutes, or until the biscuit topping is golden brown and the fruit filling is bubbling.

Remove the cobbler from the oven and allow it to cool for 5-10 minutes. Serve warm with a scoop of vanilla ice cream, if desired.
