Moka Cake

Genoise Cake A genoise cake is made with no leavening other than beaten eggs. Since this mocha cake recipe contains no butter, it can take the rich butter cream frosting without becoming overwhelming. French Buttercream French buttercream frosting is made with lots of egg yolks, which will need to be as fresh as possible. It is a little tricky to make, but well worth the effort. This is not a good frosting to make on hot or humid days. It should be at room temperature for easy spreading and decorating, but then should be immediately refrigerated.
