Preheat the waffle iron: Set it to medium-high. Lightly brush or spray with oil to prevent sticking.
Blend the wet ingredients: In a blender, add 1 cup cottage cheese, 2 large eggs, 1/2 cup milk, 1 tablespoon oil or melted butter, and 1 teaspoon vanilla if using. Blend until smooth.
Add the dry ingredients: To the blender, add 1 cup flour, 2 teaspoons baking powder, 1–2 tablespoons sugar or honey (optional), and 1/4 teaspoon salt.
Pulse just until combined. The batter should be thick but pourable.
Rest briefly: Let the batter sit for 3–5 minutes so the baking powder activates and the flour hydrates.
Cook the waffles: Pour batter into the hot iron, spreading to the edges without overfilling. Close the lid and cook until steam subsides and the waffle is deep golden and crisp, about 4–6 minutes depending on your iron.
Keep them crisp: Place finished waffles on a wire rack (not a plate) while you cook the rest.
This prevents sogginess.
Serve: Enjoy hot with maple syrup and berries, or go savory with a fried egg, avocado, and hot honey.
