Cake Mix Cinnamon Rolls

I haven't tried these yet but I'll put it on here and make it when I get a chance.

1 white or yellow cake mix

2 pkg. yeast

1 tsp. salt

2 c. flour

Combine above ingredients. Add 2 1/4c. hot water. Mix. Add 3 cups flour and knead until well mixed. Let rise until doubled. Push down and roll our into large rectangle. Mix butter, cinnamon, and sugar; sprinkle over dough. Roll up and cut in 1 1/2 inch slices. Let rise until doubled. Bake at 350 for 20 mins. Frost with powdered sugar frosting while still warm. Makes about 18 rolls.
