This is my own concoction. I am sure someone else did it before me but I have yet to read about it.

Here is my recipe for mock-chocolate mousse:

1/2 Cup Heavy Whipping Cream
4 packets Splenda (modify to your taste)
1 heaping tablespoon of Cocoa powder

Blend the ingredients in a mixing bowl.
Mix until it achieves whipped cream consistency (on high approx 1 minute)
Once the consistency is achieved, scoop into dessert dishes.
Freeze for 15 minutes or refrigerate for one hour
Serve

I tried this "recipe" this evening. It was "da bomb." According to my calculations it has about 2 grams of carbs per serving. These are actual carbs...not net! The heavy cream and splenda have 0 carbs. The cocoa powder has 4 grams per serving. Diluted in the cream it reduces the amount of carbs to about 2 per serving. These are my calculations. Check the label for yourself.
