Preheat oven to 350°. Place cherries in an 8-in. square baking dish coated with cooking spray.
In a small bowl, mix flour, 1/4 cup sugar, baking powder and salt. Add milk and melted butter; stir in just until moistened. Spread over cherries.
In another bowl, mix cornstarch, cinnamon and remaining sugar; sprinkle over batter. Mix boiling water and almond extract; pour slowly over top. Bake, uncovered, 45-50 minutes or until top is golden brown and filling is bubbly. Serve warm.
