Preheat the waffle iron to medium-high heat and apply non-stick cooking spray.
Place cottage cheese, rolled oats, eggs, baking powder, vanilla extract, maple syrup, and salt into a high-speed blender.
Process the mixture on high speed until the batter is completely smooth and homogeneous, approximately 45 to 60 seconds.
Pour 1/2 cup of batter onto the preheated waffle iron.
Close the lid and cook for 3 to 5 minutes until the steam subsides and the waffle is golden brown and crisp.
Carefully remove the waffle using a silicone spatula and repeat the process with the remaining batter.
Serve immediately to maintain texture.
