Two mousse chocolate cake

A delicious and beautiful cake for times of celebration

Last year I took a patisserie course in Paris and, just before Christmas, I learned this wonderful cake recipe. I made it for my family’s Christmas party last year…and it took me one year to post the recipe online. Actually, I’ve made this cake already 3-4 times since then, including for my birthday, and it is one of my favourite recipes now! It is composed with several different layers, the best ones being combination of white and black chocolate mousses.  Go ahead and dare preparing a spectacular and challenging dessert this Christmas!
