Preheat the waffle iron.
Allow the hard-boiled eggs to come to room temperature and remove the shells.
Add the hard-boiled eggs, raw eggs, coconut flour, sugar, baking powder, vanilla extract, and sea salt to a blender.
Blend until the batter is completely smooth and evenly combined.
Allow the batter to rest for about 5 minutes so the coconut flour can absorb the liquid and thicken the batter.
Grease the waffle iron with butter, coconut oil, or olive oil.
Add the appropriate amount of batter for your waffle maker.
Cook until the waffles are golden and cooked through.
For crispier waffles, leave them in the waffle iron slightly longer.
Serve warm with your favorite toppings.
