Sift powdered sugar in a 15"x10" rectangle on a cloth. When cake is done, immediately loosen from sides of pan; turn out onto cloth. Peel off wax paper. Starting at narrow end, roll up cake and cloth together; cool completely on a wire rack, seam side down.

If frosting is soft, chill cake before serving. Garnish with fresh mint and fresh cranberries.
