Heat the oven to 400 F. Place sliced peaches in 8x 8-inch baking pan. Sprinkle with 2 tablespoons sugar. Set aside.
In medium bowl, add remaining sugar and flour. Stir to combine; create well in center. Add egg and melted butter. Stir just until flour is moistened.
Place spoonfuls of batter evenly on top of peaches. Bake for 35-40 minutes or until top is golden brown. Serve warm with vanilla ice cream, if desired.
