How to make
Mix all the dry ingredients and add them gradually to the pre-beaten eggs and sugar. Stir it with a spatula until the mixture becomes homogeneous. Finally add the drained from the syrup fruits from the jam.
Cover a cake form with buttered baking paper and pour in the mixture. Put it to bake in a preheated 320°F (160 °C) oven for about 50 minutes. If necessary, cover the top with foil to prevent burning and check readiness with a stick. Do not bake the cake longer than necessary because it will dry out.
Let the finished cake cool completely, and in the meantime, make the ganache by melting both types of chocolate and the butter in a water bath. Slightly cool the cream and mix in the mascarpone, powdered sugar to taste, pinch of salt and drops of rum flavoring.
Brush the cake with the cooled ganache.
