Stir until combined; let stand 20 minutes. In medium bowl stir together flour, baking powder, cinnamon, baking soda, salt, and nutmeg; set aside.

Alternately add flour mixture and oatmeal mixture to butter mixture, beating on low speed after each addition just until combined. Pour batter into prepared pan.
