Low Carb Chocolate Mousse Cake

A low carb chocolate mousse cake that is a delicious trio of chocolate.  A dessert for celebrations, family gatherings and holidays.

This chocolate mousse cake was lighter than I had initially expected.  The coconut sponge cake is not heavy, and the chocolate mousse is easy on the palate too.  I used a chocolate ganache for the topping, but you could opt to leave this out and perhaps sprinkle a dusting of cocoa powder instead.

This was one of my recipes that I had initially just put together without noting the ingredients and quantities, then kicking myself as the end results was delicious and definitely “blog worthy”.  I had a friend visiting the island and wanted an easy dessert that could be made ahead of his arrival.  Knowing he loves chocolate, I threw his together and then cursed myself for not remembering exactly what I did to make this chocolate mousse cake. Eventually I had a play and came up with this version.

If you want to serve this on the same day of baking it, make this first thing in the morning.  By the early evening, the chocolate mousse and ganache will have set whilst the chocolate cake will still be fresh and light.

The rum used in this chocolate mousse cake is purely optional but almost essential in the Caribbean!  I sprinkled some rum over the cooked chocolate sponge cake and added a dash or two to the chocolate mousse.  The rum flavour was not overpowering but gave this chocolate mousse cake a holiday flavour!

This cake is a must for chocolate lovers and could be happily served up to your family and friends without them knowing it’s a sugar free and grain free option.   At the end of the day it’s purely a low carb chocolate cake with a chocolate mousse topping and garnished with a chocolate ganache!  Three levels of chocolate goodness to enjoy!
