Start by preheating your mini waffle iron. While it's warming up, gather your ingredients.
In a blender, combine the eggs, cottage cheese, softened cream cheese, vanilla extract, and your chosen low-carb sweetener.
Now, add the shredded mozzarella cheese, almond flour, unsweetened cocoa powder, and baking powder to the blender.
Blend everything together until the mixture is completely smooth. You might need to pause and scrape down the sides of the blender with a spoon.
Gently fold in the sugar-free chocolate chips by hand or briefly pulse in the blender until just combined.
Lightly grease your hot waffle iron. Spoon about 3 tablespoons of the batter onto the waffle iron.
Cook each chaffle until it reaches a beautiful deep brown color. Don't worry if your waffle iron's "ready" light turns on early; just ignore it until they are nicely browned.
Carefully remove the cooked chaffle and continue with the rest of the batter until all your delicious chaffles are made!
