I once tried the chocolate shake as a mousse, and I could only just finish it tbh, really hated it, was far too... er... sweet I guess, but I know people enjoy/love them, so I guess you'd just have to find out for yourself
But my personal feelings towards them are not good! lol
If I do a "mousse" I don't have it thick, I have it more like runny custard. Then you can still eat it with a spoon and its not as sickly sweet. Too thick it tastes like cake mix and makes me feel ill but each to their own, try it you might like it and if not dilute it x
I always have choc mousse as my treat at 8pm every evening as i have two choc shakes in the day.I personally love it as I do make it very thick like cake mix. I feel really full and satisfied then. I like it as a treat.
