Frozen Blueberry-Banana Protein Cream Pies. I used a mini cheesecake pan for these. There is 1/2 Tbs. of chopped walnuts on the bottom of each little pie. For the filling: blend in blender, 3 bananas, 1 cup greek yogurt, 2 scoops vanilla Jay Robb whey. Pour filling over the walnuts. I put fresh blueberries on the top of these, and froze for 4 hours. To remove easily, run the bottom of pan under hot water.
