Fat free chocolate mousse

1 cup of non-fat plain yogurt
2 packets splenda (I used a rounded teaspoonful)
1/2-3/4 package of SF/FF double chocolate pudding mix. (I used ½ packet, you could use any flavor of Sugar Free/Fat Free pudding mix)
2 Tbsp FF Cool Whip (I used lite cool whip)

Mix well...as you mix it, the consistency totally changes from that of yogurt to more than a pudding...it really is more like a mousse and IT'S WONDERFUL!
