Heat the oven to 350°F, place the butter in a 9-by-13-inch dish and melt it in the oven for 5 minutes.

Whisk the self-rising flour, sugar and milk until mostly smooth.

Pour the batter over the melted butter without stirring, then arrange the drained peaches over the batter without stirring again.

Bake for 45 to 50 minutes until the crust rises around the fruit and turns deep golden.

Rest 25 minutes before spooning into bowls.
