To make a chocolate layer cake, you will need the following ingredients:

To frost the cake, first place a large sheet of parchment paper under the cake to catch any drips. Then, using a large offset spatula, spread a thin layer of frosting over the top of the cake. This is called the crumb coat, and it helps to keep the crumbs from getting into the final layer of frosting. Once the crumb coat is set, add another layer of frosting and smooth it out with the spatula. Decorate the cake as desired and serve!

Use a serrated knife to slice off the top of the cake until it is level.
