dr oetker 50 calorie mousse desserts

Options
I bought two of the 3 flavours, 50 cals each makes a nice light dessert. The directions say to mix with skim milk, i bought the skim milk powder and reconstituted with water as per directions. Not sure if that was an issue but the mousse came out a lil flat. Looking for tips on how to "dress it up" what to serve with the chocolate or vanilla flavours?

How do you enjoy mousse?

Its like an airy pudding but way lighter!
