Creamy Chocolate Mousse

I got this yummy recipe from Heidi (found here), and she got it from the magazine "Simple and Delicious."  It was yummy!  I made it late last night after my kids went to bed and halved it to make 2 LARGE portions for just me and Brian.  Shhh.  Don't tell the kids.   :)  hee hee.

CREAMY CHOCOLATE MOUSSE
2 cups cold milk
1 package (5.9 ounces) instant chocolate pudding mix
1 carton (8 ounces) frozen whipped topping, thawed
1/2 cup sour cream

In a large bowl, whisk milk and pudding mix for 2 minutes. Let stand for 2 minutes or until soft-set. Fold in whipped topping and sour cream. Pour into individual dessert dishes. Dollop with whipped topping if desired.
