In large bowl, mix cake mix, 1 cup of the flour and the yeast. Add water; stir with spoon until dough forms.

Add the remaining flour 1/4 cup at a time, stirring after each addition, until soft dough forms. You may not need all of the flour. Cover with plastic wrap, and let rise in warm place until doubled, about 1 hour.

Gently punch down dough, and then reshape it into a ball. Let rest for a few minutes. Meanwhile, have melted butter ready, and in small bowl, mix brown sugar and cinnamon.

On lightly floured surface, flaten dough into large rectangle about 1/4 inch thick. Brush with melted butter; sprinkle with cinnamon sugar.

Starting with 1 long end, tightly roll up dough into a log. Cut into 12 rolls.

Grease 13x9-inch pan or 2 (9-inch) round cake pans with shortening or cooking spray.

Place rolls in pan; cover with plastic wrap. Let rise about 30 minutes while you heat oven to 375°F.

Bake 8 to 10 minutes or until golden brown. Cool 5 minutes; spread with frosting. Serve warm or at room temperature.
