In order to avoid moisture transfer the cake should be brushed over with boiling puree before icing. Adding glycerine to the icing at a rate of 0.5% will help keep the fudge icing soft and lowers the ERH of the icing, bringing it nearer to the ERH of the cake, which will also help reduce moisture migration.
