Crush the 50g marzipan into a mixing bowl, add the 20 ml rum (or water and rum extract) and mix until soft.
Separate the egg yolks from the egg whites.
Add the yolks one by one to the marzipan while whisking.
While whisking, add the butter, salt, and vanilla paste.
In a different bowl, whisk the egg whites with the sugar until stiff but don’t make them too stiff. Add some of the egg whites to the mix with the egg yolks, also some of the flour and starch, and carefully mix with a large spoon.
Repeat until the entire egg whites, flour, and starch are mixed into the yellow batter – keeping the fluffy texture of the batter.
Turn on the broil function of your oven.
Prepare a baking pan with a layer of parchment paper.
Spread a thin layer of batter into the baking pan.
Bake for a short time in the oven under the broil – careful, hot!
Remove the baking pan when the top of the batter starts to change its color to a light brown. Usually after 1-2 minutes.
Add another layer of batter and repeat the baking – layer adding – baking – layer adding … until the batter is all baked and the cake has a lot of layers.
Let the cake cool.
Melt some chocolate and heat some apricot jam.
Brush the cooled cake with a layer of apricot jam all around. Let set for a bit.
Cover the cake with the chocolate all around.
Let the chocolate set.
Cut and enjoy a heavenly slice of cake.
If baking for later:
Freeze without the chocolate and glaze after thawing.
