Combine the delicious texture of a three milk cake with the rich flavor of dark chocolate to make this Three Milk Chocolate Cake. The secret to a fluffy cake is to beat the egg yolks and whites separately and then fold them together gently; this cake absorbs the milk better and stays moist. For this Three Milk Chocolate Cake, we used a bit of hazelnut cream, an ingredient that gives it a delicious flavor. Had you thought of combining these cakes?
