Combination Creaming/Sponge Method

Some European-style cakes are begun by using the creaming method. In other words, butter is creamed with sugar until the mixture is light. These cakes usually contain no chemical leavening, however. Instead, whipped egg whites are folded into the batter, as for some sponge cakes. Examples of this kind of cake are Hazelnut Sponge Cake and Baumkuchen. Mixing hazelnut sponge is illustrated in the procedure below.
