Place the rolled oats into a high-speed blender and pulse until they reach a fine flour consistency.
Add the protein powder, baking powder, egg whites, cottage cheese, almond milk, vanilla extract, and cinnamon to the blender.
Process the mixture until the batter is completely smooth.
Preheat a non-stick griddle or large skillet over medium heat and apply a light coating of non-stick cooking spray.
Pour approximately 1/4 cup of batter per pancake onto the heated surface.
Cook for 2 to 3 minutes until bubbles form on the surface and the edges appear set.
Flip the pancakes carefully and cook the secondary side for an additional 1 to 2 minutes until golden brown.
Remove from heat and serve immediately.
