I have a regular chocolate mousse recipie which could be modified. I hate gelatin (the fact that it comes from calf hooves really puts me off), so my recipie doesn't have any.
150g dark chocolate
4 eggs, seperated,
300mL cream, whipped
Melt the chocolate, stir in the egg yolks one at a time (this is hard, the choc will go hard but if you keep going it will soften again).
Fold through the cream.
Beat the egg whites to stiff peaks.
Fold though the chocolate mix.
Refrigerate for 3hours+.
So to make is low fat, you just need slightly different ingredients.
-ommit the egg yolks, use a bit of skim milk to get the chocolate to a gnache-like texture.
-use less chocolate, like 90g. This will make it less rich (but also set less stiff). You could also add some cocoa powder to the cream for extra flavour if you do this.
-use a lower fat chocolate, or carob.
-use a lower fat substitute for the cream (anything that has the texture of whipped cream will work)
I think it would work
