A friend of mine shared this recipe that you may or may not have seen:
http://www.skinnytaste.com/2012/02/skinny-no-bake-peanut-butter-pie.html
I decided to make some myself, but altered the recipe a little. It makes it a little more like cheesecake and with less calories! You can follow the skinny taste recipe but substitute their peanut butter for PB2 and also I used a full 8 ounces of reduced fat cream cheese. I also added whipped cream on top, so I just doubled what the recipe called for and put half on top. Following my recipe, one pie = six slices. Nutrition is (based on what I track):
Calories: 192/213 with extra whipped cream
Carbs: 24grams/25 with extra whipped cream
Fat: 7grams
Protein: 5grams
Fiber: 1 gram
Sodium: 267mg
The finished product is super thick and rich and one slice easily satisfied me, which is hard for low cal sweets!
