Preheat your waffle iron.
Combine the eggs, cashews, milk, honey, vanilla, and melted coconut oil in a blender. Blend until very smooth and creamy. You may need to stop the blender and push the mixture down the sides a few times to get it all to blend really well.
Add the salt, baking soda, and coconut flour, then blend again for about a minute until the dry ingredients are incorporated into the wet.
If you’re iron requires oil, spread a little coconut oil on both sides. Pour the batter into the waffle iron so it just covers the bottom portion of the iron, being careful not to overfill it as these do rise quite a bit and will spill over.
Cook the waffles for about a minute, more or less depending on the heat of your waffle iron. If they release easily with a fork when you open the lid, they are probably done.
Repeat until the batter has been used up.
