Stack up the layers, secure with a decorative pick of your choice, and decorate.

This one is decorated with mentaiko.

I make small cutouts from a crabstick using a straw, and used them as decoration.

The third layer here is a slice of ham, and I used colored sugar dragées as decoration...

The pick I used for this one was too long, so I boosted up the bottom with lettuce leaves.

Here's another picture.

I put one in my daughter's bentos. The topping uses is sujiko (salmon roe)!

I found this at the supermarket. It's a local Kansai item called "bettora". If I make the 'cake' with this...

..see? It looke like a cheesecake!

I covered a hamburger steak with sauce and made a 'chocolate cake' version.
