This elegant cake is a showstopper, with layers of fluffy white cake and tangy passion fruit curd, all covered in a rich white chocolate ganache. The cake layers are made with a combination of cake flour and almond flour, giving them a delicate crumb and nutty flavor. The passion fruit curd is made with fresh passion fruit juice, sugar, eggs, and butter, and is cooked until thick and creamy. The white chocolate ganache is made with high-quality white chocolate and heavy cream, and is poured over the cake to create a smooth and glossy finish. This cake is perfect for a special occasion or a fancy dinner party.
