In a large mixing bowl, whisk together the eggs until they are light and fluffy. Add the full-fat coconut milk, avocado oil, pure vanilla extract, and pure maple syrup. Mix until well combined.
In a separate bowl, combine the gluten-free all-purpose flour, baking powder, ground cinnamon, and sea salt. Whisk these dry ingredients together.
Gradually add the dry mixture to the wet mixture, stirring gently until just combined. Be careful not to overmix; a few lumps are fine.
Preheat your waffle iron according to the manufacturer’s instructions.
Lightly grease the waffle iron with cooking spray or avocado oil. Pour an appropriate amount of batter into the center and cook for about 4-5 minutes until golden brown and crisp.
Carefully remove the waffles from the iron and serve warm with your favorite toppings.
