Tweak our chocolate mousse cake recipe

If you want to make changes to this great recipe you could definitely top it with a chocolate frosting but be careful with sweetness levels, you will need to add additional flavourings or cut the cake in half and add fresh fruit between the cake layers. You can also change the flavour of the coulis to cherry or to a specific berry flavour like raspberry or strawberry. Potentially the cake can be made in a couple of tins to make a layer cake, fill the cake with delicious fresh berries and cream. Due to the moist crumb of the cake it will not cope with too many layers.
