Preheat the waffle iron to a medium-high setting and lightly grease it if needed.
In a small bowl, combine the flour, baking powder, and cinnamon. Mix well to distribute evenly.
In a blender, add the cottage cheese, eggs, melted butter or oil, maple syrup, and vanilla. Blend until the mixture becomes smooth and creamy.
Pour the blended mixture into the bowl with the dry ingredients. Stir gently until just combined, making sure not to overmix. Let the batter rest for a few minutes so it can thicken slightly.
Add about ¾ cup of batter to the waffle iron, adjusting the amount based on the size of the machine. Close the lid and cook until the waffles are golden and crisp, usually a few minutes, depending on the appliance.
Carefully remove the waffles and serve while warm with toppings like fruit, syrup, nut butter, or anything you prefer.
