Start by heating the waffle maker up.
To make the chaffles begin by mixing the mozzarella cheese, almond flour, eggs, sweetener, cinnamon, baking powder and vanilla extract together.
Once the ingredients are well mixed gently stir in the blueberries. Don't use frozen blueberries as the extra moisture makes it difficult for the chaffles to get crisp.
Depending upon the size of your waffle maker pour 1/4 to 1/3 of the batter into each waffle mold. Close the cover and allow them to cook.
Start checking the chaffles after they have been cooking about 8 minutes. Carefully open the waffle maker. If the chaffels start pulling apart close it and cook for another minute or two. They are done when crispy and the waffle maker is able to be opened without pulling the chaffles apart.
