If there were a ratio of ease to popularity, this would be voted --the best peach dessert there is. If peaches are out of season, use the very best brand of frozen peaches and cut back on the amount of sugar. You may use self-rising cake flour if you omit the baking powder and salt.
1/2 cup (1 stick) butter
1 cup cake or all-purpose flour
1 1/2 teaspoons baking powder
1/2 teaspoon salt
1 cup whole milk
1 cup sugar
2 cups sliced peeled peaches, reserved in bowl
Preheat the oven to 350 degrees F.
Place butter in 13 by 9-inch baking dish. Place dish in oven to melt butter. Mix flour, baking powder, and salt in large bowl. Stir in milk and sugar to form batter. Using oven mitts, remove hot baking dish from oven. Pour batter into baking dish. Spoon peaches and any peach juices evenly over batter. Bake until batter rises and browns on top, about 30 minutes.
