Chocolate Mousse Cake

As always Christmas day requires an alternative dessert to Christmas Pudding. It’s not for everyone and it’s always nice to have a choice of pudding, especially when it involves chocolate! This Mousse cake is light but delicious chocolate dessert cake which can be easily decorated to suit any occasion, not just Christmas!

I love this cake as it’s lightness makes it perfect for any celebration. Often enough people always tend to indulge heavily in the main course so are unable to make room for dessert. However, this bake is light in both texture and flavour so, it’s not such a struggle to power through dessert! The cake is made up of a light chocolate sponge with a mousse on top of it to form the main base, it’s a great mix of textures and is packed full of chocolatey goodness. I’d recommend serving with some cream too!!

The cake can be topped with pretty much anything you like. For Christmas, I used edible silver and icing sugar for a snow effect and got a couple of edible festive characters to be in the snow scene. But, be as creative as you want to be! For summer I would pile fresh raspberries and strawberries on the top with a dusting of icing sugar. Just plan out how you are going to set your decoration out as, as soon as you make a mark in the mousse it’s hard to blend out.

The dessert is sooo easy to make and takes no time to do either. It just requires time for it to set in the fridge so make sure you make it the day before you need to serve it.
