Cut biscuits into quarters and set aside. Pour sugar and cinnamon into a large ziplock bag and set aside with cut biscuits.
In a small pan, melt butter, sugar, water and salt together. When mixture begins to boil, remove from heat and pour ⅓ of sauce in the bottom of a greased casserole crock pot.
Place the cut biscuits in the bag of sugar and cinnamon. Shake to cover the biscuits and then put the biscuits evenly over the sauce in the crock pot.
Finish by pouring the remaining sauce over top of the biscuits.
Place the lid on the crock pot and cook for 2 hours on high heat.
