Do not overbeat. (Batter will be fairly thin.) Pour batter into prepared pan. Bake at 180 degrees C℉ (180℃) for 35 to 50 minutes, or until cake springs back in center when touched lightly with finger or until wooden toothpick inserted in center comes out clean. Cool 5 minutes before removing from pan.
