I have swapped apple sauce for oil in baking recipes before, but this time I was looking for something different to make and was checking out their apple recipes. I came across their Apple Cinnamon Smoothie. It sounded so good but I didn't have any vanilla yogurt on hand. I searched my refrigerator and freezer and thought to myself...what goes with apples? Caramel, what else! Lo and behold, I had some caramel swirl frozen yogurt.
