Turn the dough out onto a floured work surface and cut it into 4 pieces. Roll each piece out to a 1/2-inch dowel and fashion into small circles, or wheels, measuring 3-inches in diameter.

Remove them carefully with a slotted spoon and drain on paper towels. Sprinkle with confectioners' sugar and serve.
