I've used cake mix to make cookies before but never heard of making rolls from it. Interesting.

Here is one I have in my file, but I have never made it:

Overnight Cinnamon Breakfast Rolls
1 18 oz box of vanilla cake mix
5 1/4 c flour
2 pkg (or T) dry yeast
1 t salt
2 1/2 c warm water
1/2 c sugar
2 t cinnamon
1/2 c butter, melted
1/2 c raisins (optional)
3/4 c chopped pecans (optional)
1 c powdered sugar
3 T milk
1/2 t vanilla
STIR together first 5 ingredients in a large bowl. Cover and let rise in a warm place for 1 hour.
COMBINE 1/2 c sugar and cinnamon
TURN dough onto floured surface. Divide in 1/2. Roll one portion into an 18 x 12 inch rectangel. Brush with half of butter and sprinkle with half of sugar mixture, half of raisins and 1/4 c pecans.
ROLL up starting at long end. Cut into 16 slices. Place into lightly greased 13x9 inch pan. Repeat procedure with remaining rectangle. Cover and chill 8 hours.
REMOVE from refrigerator and let stand 30 minutes.

STIR powdered sugar, milk and vanilla. Drizzle over rolls. Sprinkle with remaining pecans. Yield, 32 rolls.

Nodakgirl posted one using frozen bread. Sounds great.

Got this recipe for cinnamon rolls from a Tupperware party at least 35 (Gulp!) years ago and it's been a family favorite ever since.

Cinnamon Rolls

2 pkg yeast
2 cups warm water
Box of white cake mix
4 cups flour

Filling

1 stick butter or margarine (melted)
Sugar to your taste *
Cinnamon to your taste *
Walnuts (optional)

Vanilla Frosting

* I keep a big shaker bottle of sugar/cinnamon mixture in the cupboard for toast, cereal, etc., not sure of the exact ratio.

Dissolve 2 pkgs yeast in 2 cups of warm water in large bowl. Add box of cake mix and 4 cups of flour. Mix well. Let rise to double, about one hour (in my oven, just barely turned on).
Roll flour mixture into large rectangle on a floured surface, to about 1/4 to ½ inch thick. Pour melted butter along center of rectangle and spread to edges until entire surface is covered with butter. Sprinkle with sugar and cinnamon (I spread it on pretty thick) and add nuts if desired. Very gently roll the rectangle into one (lengthwise) log. I use a floured spatula to lift and roll, lift and roll, etc. Cut roll into 3/4 inch slices. Let your rolls rise for another 45 minutes and bake 20 minutes at 350 degrees. Frost with vanilla frosting while still warm.
