In comparison I guess mousse and cheese are lower in calories. The taste of mousse is lighter, cheese is healthier, lower in calories compared to chocolate and cream, and tastes great. But there are light cheese and heavy cheese, light cheese is healthier, lighter, and the flavor is also very good, heavy cheese calories are higher, but eat a little bit of a sense of satiety, more greasy.
Chocolate and cream (I don't know what cream you are talking about, the usual cake on the kind of whipped cream, there are animal cream and vegetable cream, the calories are very high and add a lot of sugar, animal cream taste better, according to the raw material that cream is butter, butter calories are also quite high) of the calorie that is needless to say.
