You can never have enough chocolate with your chocolate cake.
- Preheat oven to 350°F (180°C).
- Blend cake mix, eggs, water and vegetable oil. Divide batter among three greased 9-inch (23 cm) cake pans. Bake for 23 to 28 minutes or until toothpick inserted in centre comes out clean; let cool completely.
- Spread frosting evenly between each layer of cake, making 3 layers. Spread remaining frosting over entire cake. Decorate with piping bag.
