Preheat oven to 375°F (191°C). Place the butter in an 8×8-inch or 9×9-inch baking dish and set the dish in the oven to melt the butter completely while preparing the batter.
02 -
In a medium mixing bowl, whisk together granulated sugar and all-purpose flour until homogeneous.
03 -
Gradually add whole milk to the sugar-flour mixture, whisking continuously until a smooth, thick yet pourable batter forms with no lumps remaining.
04 -
Carefully remove the hot baking dish with melted butter from the oven. Pour the batter evenly over the melted butter without stirring; allow the batter to float atop the butter.
05 -
Open the can of sliced peaches and pour both the fruit and syrup evenly over the batter. Do not mix; leave layers undisturbed.
06 -
Transfer the assembled dish to the oven and bake for 40–50 minutes, checking at 40 minutes. The top should be golden brown and the edges bubbling. Batter will rise around peaches, forming golden crust and syrupy filling.

Remove from the oven and let cool for at least 10 minutes before serving to allow the cobbler to set and prevent burns.
