Prepare the pastry shells according to the package directions.
Beat the cream and confectioners' sugar in a large bowl with an electric mixer on high speed until stiff peaks form. Fold in the creme fraiche.
Spoon 2 tablespoons whipped cream mixture into each pastry shell. Top each with 1 tablespoon berries. Repeat the layers. Top each with 1 tablespoon whipped cream mixture and 1 berry. Sprinkle with additional confectioners' sugar, if desired.
