Easy Peach Cobbler

Preheat oven to 350 degrees F. Coat an 11-by-7-inch glass baking dish with cooking spray.

Whisk flour, sugar, baking powder and salt in a large bowl. Add milk and butter; stir until thoroughly combined. Pour the batter into the prepared baking dish; top evenly with peaches.

Bake until the top is golden and set, about 1 hour. Cool on a wire rack for 10 minutes. Serve warm.
