Notes
We prepare the ingredients for the cream as the first step, because it needs to cool well
We prepare the cake as shown in the video
Tray size 30 and we can use any rectangular or square tray
We leave the cake to cool completely
We can water the cake with a cup of cold milk if we want it soft. I prefer it fragile
We whip the cream, add the envelope of the cream chantilly, and beat a little, as the cream does not have to become heavy
We can adjust the texture of the cream by adding a little milk if necessary
We put the cream on the cake and grate the chocolate using a peeler or a knife
So we leave it plain or a sprinkle of cocoa or nuts according to your desire
Cool, then serve. Try it 😋😋
