Make whipped cream using 2 cups heavy cream, 2 – 3 TBL confectioners’ sugar and 1 – 2 tsp vanilla. Spread 1/2 TBL whipped cream on each cookie in a box of Famous Chocolate wafers, building up a stack. Arrange two 7-inch stacks next to each other (on their sides) on a plate to form a cake. Cover generously with remaining whipped cream. Refrigerate overnight. Serve, cutting on diagonal.
