                In a large bowl, whisk together whole wheat flour and ground cinnamon to eliminate any lumps.
              
              
              
                03 - 
                In a separate bowl, whisk eggs and unsweetened applesauce until the mixture is smooth and homogenous.

                Fold the shredded apple gently into the wet ingredient mixture, taking care to maintain the mixture's texture.

                Gradually add the wet mixture to the dry ingredients, mixing until just combined to avoid overmixing. Add water as necessary to achieve a thick but pourable batter.
              
              
              
                06 - 
                Pour the batter into the prepared pan, smooth the surface, and bake for 25 minutes or until a toothpick inserted into the center emerges clean.
