Place the apples, water and cinnamon into a medium saucepan and heat over medium heat until the water starts to boil.
Reduce the heat to low and simmer, cover, and cook for 15 minutes or until apples are tender when pricked with a fork, stirring occasionally. Let cool slightly.
Transfer all of the ingredients into a blender or food processor and puree on high for 1-2 minutes or until the puree is completely smooth. If puree is too thick, you can add in addtional water in 1 tablespoon increments.
