Add water, oil, vinegar and vanilla. Beat with a fork just until all dry ingredients have been moistened. Bake cake 35 to 40 minutes or until center springs back when gently pressed. Cool cake in pan 5 minutes. Remove to serving platter. Cover and set-aside until ready to serve. Just before serving, sift confectioners' sugar over top. Cut into 4 squares; cut each square diagonally in half to make 8 triangular pieces.
