For the marzipan cake, mix the marzipan and the amaretto or water with a spoon, mix with butter, sugar, vanilla sugar and the 3 yolks. Add enough milk to make everything nice and creamy.
Then stir in the flour sifted with baking powder and fold in the snow. Bake in a buttered and floured or floured pan at 160 degrees Celsius (hot air). The duration depends on the form. Cake in a wreath form (about 30 minutes), in a loaf pan it takes a little longer (about 45 min).
The cake rises quite well, but collapses again a bit. The marzipan cake is nevertheless very fluffy.
If you have fresh apricots at hand in season, you can also add some apricot pieces to the mixture – the apricots harmonize perfectly with the marzipan.
