For topping, combine sugar, flour, oats, cinnamon and nutmeg in a medium mixing bowl; mix well. Cut in butter to make a crumbly mixture. Set aside.

For batter, combine flour, sugar, baking powder and salt in a large mixing bowl. Cut in butter until mixture resembles coarse crumbs. Add eggs and milk; mix just until dry ingredients are moistened. Do not overmix; batter will be lumpy. Spread half the batter into a lightly greased 13 × 9 × 2-inch baking pan. Spoon cherry filling evenly over batter. Top with remaining batter. Sprinkle reserved topping over batter.

Bake in a preheated 350º oven 30 to 35 minutes, or until golden brown. Serve warm.
