Double Chocolate Mousse Cake

Double Chocolate Mousse Cake, is a moist Chocolate Cake topped with a white chocolate and dark chocolate mousse. Creamy, decadent and delicious. The perfect Special Occasion or Just Because Cake. So Good.

It was my daughter’s birthday a couple of weeks ago and to celebrate she chose a Skor No Bake Cheesecake with a Caramel drizzle. I also decided to serve this Chocolate Mousse Cake as a delicious second choice.

We are a cake loving family, so whenever birthdays roll around I let them decide on what their cake of choice is.

My daughter loves cheesecake and I have to totally agree with her. So when she decided on a Skor Cheesecake with a Caramel drizzle I knew it would become a family favourite.

And I have to say a friend favourite too, that cake was gone, no left overs for us! It’s a good thing I made a second cake.

This cake was actually one of my choices. I love mousse and of course chocolate cake.

Italians are not big on lots of frostings and overly sweet, so I thought a mousse topping would be perfect.

This Double Chocolate Mousse Cake would include everyones favourite chocolate. My daughter (the birthday girl) adores white chocolate and my husband and myself enjoy dark chocolate.

This Chocolate Mousse Cake is the type of cake where you can leave it plain and it’s so good as is or you can fancy it up with some fresh fruit or how about a simple chocolate ganache poured over the top?

  1. You mention leaving the cake in the pan to assemble it. The photo shows it out of the pan. What type of cake pan did you use?

    1. Hi Gwen, I assembled the cake in a springform pan (as shown in the process shots) then I removed the cake for the final photos. Hope that helps. Take care!
