Coffee Chocolate Mousse Cake

It’s been known for years now that whenever someone has a birthday party – I’m the one to bring on the cake. I love making birthday cakes for my close friends and family and always happy to make a new, exciting festive cake that will be just right for the celebration.

I made this coffee chocolate mousse cake for my mother’s birthday, and to tell you the truth – this is definitely one of the best chocolate mousse cake recipes I ever made. It’s decadent, chocolatey and has become my family’s favorite cake for birthday.

This chocolate mousse cake is made of a soft chocolatey brownie bottom, topped with luscious chocolate mousse and espresso and white chocolate whipped ganache on top. For decoration I made chocolate nougatine tuilles, which made this cake even more decadent and pretty.
