Preheat your waffle iron to medium heat, which is essential for achieving that perfect crispy exterior while keeping the inside fluffy.

Whisk together in a medium bowl the white whole wheat flour, baking powder, cinnamon, and salt.

Blend the eggs, milk, melted butter, applesauce, vanilla extract, and packed spinach in a blender until smooth.

Combine the spinach mixture with the dry ingredients in the medium bowl, stirring gently.

Pour 1/4 cup of the batter onto the preheated waffle iron and close the lid. Cook until they are golden and crisp.

Serve immediately or store them in an airtight container in the fridge or freezer.
