Combine cake mix, flour, warm water, and yeast in a large mixing bowl.
Once dough forms, place dough on a flour-dusted surface and knead until the dough "bounces" back after touching it.
Place dough into a large glass bowl and brush the top of dough, as well as the sides of the glass bowl, with a Tablespoon of oil.
Cover bowl with a kitchen towel and allow to sit for an hour.
After an hour, the dough should have about doubled in size.
Remove dough from bowl and place onto a floured surface. Use a rolling pin to roll dough out to about 1/8 inch thickness.
Brush melted butter onto the dough and sprinkle with the cinnamon and sugar.
Use hand to roll dough sheet into a log, then slice into rolls.
Place rolls into a baking dish and cover again for another hour.
Preheat the oven to 350°F.
Bake the cinnamon rolls for 30 minutes.
