Tailoring:

1. Cut the cooled cakes in two layers. The chocolate cake is cut in three layers. Cut the third layer in small pieces and store in an air tight container. Have the pieces on their own. Perfect tea deserts.

2. Use two different size glasses or bowls. Using the bigger bowl, cut out the bigger insert of both - white and cocoa cakes. Cut out the smaller inserts from the first cut cakes. 

3. Place the bigger white cake inserts in the chocolate rings, and fill with the chocolate smaller cakes. Fill the white cakes ring with the chocolate bigger cake and fill with the white small cake insert. 

4. Assemble the cake, spreading the chocolate ganache on each layer, making sure the checkmate effect is achieved.

5. Glase top and sides of the cake with the rest of the ganache.
