Combine the warm water and yeast and let sit while preparing dry ingredients.
Combine cake mix, flour and salt in the bowl of a stand mixer.
Add the yeast mixture, beaten eggs and vanilla and knead for 4-5 minutes.
Place the dough in a greased bowl and loosely cover with plastic wrap. Let it rise 45-60 minutes until it doubles in size.
Punch down the dough and place on a floured surface. Roll it into a rectangle about ¼ inch thick. Spread softened butter over the entire surface and sprinkle with brown sugar and cinnamon.
Roll tightly into a large roll. Cut into 24 rolls and place in two 9x13 greased baking dishes.
Bake at 375 degrees for 20-25 minutes, depending on how thick you cut the rolls.
Remove from oven and frost with Salted Caramel Cream Cheese Glaze.
