Beat the eggs with the sugar. Add the flour to the baking powder. Bake a layer and once it cools, cut it into 2 thinner ones.
Sweeten the yoghurt to taste. You can flavor the coffee with a few drops of rum flavoring. Moisten one cake layer with coffee and smear it with half the cream. Place the sliced fruit on top of the cream. Place the other cake layer on top. Again soak with coffee. Dab with the remaining cream on top and decorate with fruit.
