Now divide the mixture between the two pies. Prepare sweetened whipped cream with the remaining whipping cream and 1/3 c. of powdered sugar and spread it on top of the two pies.
Place the clear plastic shells back on the pies and allow to chill for several hours. This is actually really important–I tried eating it right away once and the pie wasn’t banana-y at all and the moisture hadn’t absorbed into the crust, so the crust just fell apart. And there you have it–the best AND the easiest banana cream pie you’ll ever have or need!
