Add the eggs, rolled oats, cottage cheese, and vanilla protein powder to a high-speed blender.
Blend on high until the batter is completely smooth with no clumps, scraping down the sides as needed.
Preheat the waffle iron according to the manufacturer's instructions.
When hot, pour enough batter onto the waffle iron to cover the grid (use a few spoonfuls depending on your iron).
Cook until the waffle is crispy at the edges and cooked through, then remove with a spatula and repeat with remaining batter.
Serve the waffles immediately with your preferred sweet or savory toppings.
