  In large bowl, mix cake mix and 2 cups of the flour. Add water-yeast mixture; stir with wooden spoon until dough forms. Add remaining flour 1/4 cup at a time, stirring between each addition, until it comes together in a ball. You may not need all of the flour. Cover with plastic wrap, and let rise in warm place until doubled, about 1 hour.
