Just an interesting idea. As I understand it, organic peanut butter's fats are better for you than regular Skippy-type PB fat? Anyway, if peanut butter is tolerable for your diet, try:
Lite cool whip ~2 big spoonfuls, YMMV
1 scoop ON protein powder
2 tbsp organic peanut butter
Put the cool whip in a bowl, microwave on high for ~14 seconds, then put in powder and stir until it becomes liquidy and they're fully mixed. Then, one at a time, stir in 2 tbsp organic peanut butter (organic since it flows more and could probably stir a little easier) into bowl until well mixed.
