Preheat your waffle maker according to its instructions.
In two separate bowls, carefully separate the egg whites from the yolks.
In the bowl with the egg yolks, add the melted butter, almond milk, vanilla extract, and almond extract. Whisk until smooth.
In a separate bowl, mix together the coconut flour, baking powder, and granulated sweetener.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Using a clean whisk, beat the egg whites until they form stiff peaks.
Gently fold the whipped egg whites into the batter using a spatula.
Pour the batter into the center of the waffle iron, close the lid, and cook according to your waffle maker's instructions, usually about 3-5 minutes.
Once cooked to a golden brown, remove the waffles carefully and serve immediately.
