1. Place chocolate in a large microwaveable bowl. Melt in microwave for 2 minutes, stirring every 30 seconds. Stir chocolate until smooth.
2. Once chocolate cools, add 1 cup of Cool Whip to the chocolate, stirring quickly. Continue folding in the rest of the Cool Whip in 2 batches, until there are no visible streaks.
3. Divide mousse into thirds. Place one-third of the mousse into a medium-size zip-locking plastic bag, cut off one corner, and pipe mousse onto 6 spoons, about 1 tablespoon per spoon.
4. Top with your favorite toping, such as toasted coconut, slivered nuts, or crushed candy.

Serves 6 (makes approximately 18 spoonfuls).
