Though I've baked all sorts of pastries, cakes, cookies, and crazy complicated confections during my tenure in a pastry lab, I've always had a soft spot for Swedish princess cake. Of obvious European origin, this cake got its name from three princesses that loved the cake. A traditional Swedish Princess cake consists of airy sponge cake, pastry cream, a thick dome of whipped cream, and is covered in marzipan. There are many variations of this cake with slightly different fillings, and colored marzipan. In any case, this multi-layer sponge cake is fit for royalty.
