This Ultimate Chocolate Mousse Cake is made with a chocolate sponge and a Baileys Chocolate mousse filling, topped with Chocolate ganache.

I was inspired making it after watching Julie and Julia film.
I have waited eagerly the past few months for the film Julie and Julia to come out in the theatres in Greece and finally it came out on Thursday, so I couldn’t wait any longer and my husband and I went on Saturday evening to see the film.
I am sure that by now you have all heard about this film, which is based on two books: My life in France, which is the autobiography of Julia Child and Julie Powell’s book: Julie and Julia.
Julie worked as a Secretary for the Government and at a certain point of her life she was fed up of everyday life and wanted to challenge herself and do something different.
Discussing it with her husband she decided to create a blog, back in 2002 and cook all 524 recipes of Julia Child’s Mastering the Art of French Cooking in 365 days and blog about it.
Back in 2002 I didn’t even know what a blog was but I can relate into a lot of incidents in the film when in 2007 I had to close my bookshop, as business wasn’t going well and since I couldn’t find a job, I was feeling very bored at home, so I also started blogging about something I really enjoyed doing and that was cooking!
The movie was fantastic. It was hilarious and so pleasant to watch, taking us to a wonderful journey of tastes, sensations and emotions.
The only thing that didn’t seem right and bothered me was Meryl Streep’s accent.
Before the release of the film I had never heard of Julia Child before and of course, knew nothing about her.
The following day I google searched to see if I could find a video to see how Julia Child really was and was pleasantly surprised to see how well Meryl Streep had impersonated her.

The funny thing about the video is that Julia Child is making chocolate mousse!!
I wish I had seen this video before making mine!!!
Today it’s time for celebration as it’s my husband name day. As Julia said to her husband “You are the butter on my bread and the breath to my life”.
Thanks Demetri, for your love, your support and understanding. Inspired by the film, today I will be cooking one of his favourite dishes Boeuf Bourguigon and yesterday I made this lovely Chocolate Cake for him.
Hope you enjoy my cake. I may have not graduated from the Cordon Bleu but after two years of blogging, I have graduated the “Blogging School” as everyday we learn something new and I feel very proud that I can now make creations of my own.
Hope you’ve enjoyed and as Julia used to say “Bon Appetit”!!
I wanted to make something different so instead of cutting the cake horizontally, I cut it vertically into six stripes, removing from each piece 1 cm of cake to fill it in with the cream.
You can use these leftover pieces to make a few truffles or a trifle or call your kids and eat it as it is 🙂
How I made the Ultimate Chocolate Mousse Cake
To make the ultimate chocolate mousse cake, I made a sponge cake which was cut into two pieces.
I then wet them with some syrup and baileys liqueur and then joined them together with a thin layer of cream.
It is better to make the sponge cakes from the previous day as it can be cut much easier.

For the cream, I had seen a chocolate mousse on Chapot’s blog and I envisioned the cake with some mousse in it.
However, I had never made mousse before and I don’t remember French as I used to, so I must have done something wrong and when I added the yolks to the melted chocolate it became very stiff, so the first thing that came to my mind was to add some heavy cream.
That made it creamy again but when I added the beaten egg whites, it didn’t come out as mousse at all. However, that didn’t discourage me, I found other ways to use it.

Some of this mixture was mixed with some whipped cream to form the filling and the remaining was mixed with the chocolate ganache to cover the cake on top.
Result: The title says it all. This was the most delicious yummy, indulgent ultimate chocolate cake I have ever tasted in my life, lots of ingredients, a bit fussy to make but so worth it.
I served this ultimate chocolate cake with some syrup from the poached grapes and you cannot imagine how the spicy, peppery sauce matched with chocolate. If I had thought of it before I would have decorated the cake with some of the grapes.

Hronia Polla for your Dimitri, It is a special day for me- my dad was Dimitri( James), and we now have his grandson, Demetrius Constantine. I went to liturgy at St Demetrius in Mystra, where the last Paleologus was crowned. I spent the day walking, going to the Castle, seeing the nuns & cats of Pantanassa monastery, then I walked down to the Xenia restaurant where my husban's cousin, the chef treated me for dinner! I hope you had a beautiful day! The lemons are getting ready in the garden- I shall have to try the cake. Ivy, I wish you could have been with us when we ran our Greek restaurant in Amherst Mass-using up your mistakes is integral! Julia Child really saved cooking for the US. Her library is now at Radcliffe( Harvard)- She went to Smith College, the women's college near us!

The white stripes in between look cool.... Heard about the movie earlier from The Little Teochew, I think I will wait for the DVD.

Absolutely devine! Your husband is lucky to have you. :-) And happy name day to your husband!
I have only recently heard about Julia Child and I am dying to get her books (hubby is the obstacle - he says I have too many cookbooks). Every since I moved to Germany I don't keep track of new movies that come, but Julie and Julia sounds like something I would love to watch.
I think it was a clever idea that you cut the chocolate cake vertically rather than horizontally. It makes for a beautiful presentation and your last photo looks scrumptious. :-)
