The glorious dessert intersection of pie and cheesecake collides in this deliciously rich and creamy creation. Press a crust of crushed vanilla wafer crumbs, walnuts and butter into a springform pan and fill with a mixture of cream cheese, sugar, flour, eggs, sour cream, mashed banana, banana liqueur and vanilla. Bake in a water bath for optimal tenderness. Next, create a pastry cream layer by mixing gelatin with warm milk, sugar, egg yolks and vanilla, then fold into whipped cream. Top the cheesecake with more vanilla wafers, then the vanilla cream, then delay no longer and indulge in a large, dreamy slice! Get the recipe for Banana Cream Cheesecake.
