Added other flavor in Opera cake.Amazing! And neat layers.

Hi. This is Joconde.
This cake is the Opera Cake everyone loves.
However, most of the opera cake recipes seem to be the same.
So I modified it a bit.
It tastes similar to a classic opera cake, but it’s slightly different.
It's not too sweet at all. I think it's just the right amount of sugar for an opera cake.
I am sure you will love it.
I recommend you watch the video and try making it.
Notice
I used ganache frame because I wanted to make a cake with neat layers.
The sheet was cut to fit the size of the tool, so there were scraps.
However, if you want to do it without wasting, divide the entire sheet into 4 equal parts.
You can make it in 4 layers: ganache - buttercream - ganache - buttercream.
At this time, except for the chocolate biscuit sheet and chocolate glaze.
Caramel, buttercream, and ganache should be increased to 1.5 times the amount of the recipe below.
