"Extra-virgin olive oil, also known as EVOO, helps to give this cake a very rich and complex chocolate flavor and a fine, moist texture.

If you have both a handheld and a stand mixer you can beat the batter with the handheld mixer and use the stand mixer for the egg whites. Otherwise, wash your mixer and/or beaters very carefully before beating the egg whites...."
