Preheat the oven to what is stated on the biscuit package. Place crushed pecans in the bottom of a 9-inch pie pan. Pour caramel over the pecans and sprinkle cinnamon over the caramel. Pour sugar mix in a Ziplock bag. Separate biscuits. Place a biscuit in the bag, shake, and makes sure it is covered with the sugar mixture. Place biscuit over the topping in the pie pan. Repeat with all the biscuits. Make sure they are touching in the pie pan. Bake according to directions on the biscuits or until golden brown and cooked through. The baking time could definitely be longer than the suggested time on the package. Just watch them and make sure they are cooked through. Once baked, invert sticky buns onto a plate for serving. Serve warm.
