In a small saucepan over medium heat, bring cherries and 1/3 cup sugar to a boil. Remove from the heat; set aside.
In a small bowl, combine the flour, baking powder and remaining sugar. Cut in butter until mixture resembles coarse crumbs. Stir in milk just until moistened. Spread into a greased 3-cup baking dish; pour cherries over the top.
Bake at 375° for 25-30 minutes or until bubbly and edges are golden brown. Serve warm.
