Simply stir all ingredients (except cocoa) briefly with the mixer. Grease the loaf pan. Pour 2/3 of the batter into the mold. Stir in a little cocoa and amaretto into the remaining third. Place on the light dough and pull through both doughs with a fork. Place in the oven preheated to 175 ° and bake for approx. 50 minutes.
Mix the powdered sugar and enough amaretto to make a thick pouring and pour this onto the cooled cake.
