Add 1 cup cottage cheese, 1/2 cup milk, 2 eggs, 2 tablespoons light olive oil, 2 tablespoons maple syrup, and 1 teaspoon vanilla extract to a blender or food processor. Blend until completely smooth and the cottage cheese curdles have disappeared completely – this usually takes about 15-30 seconds.
Add 2 cups almond flour, 1/3 cup gluten-free flour, 2 teaspoons baking powder, and 1/4 teaspoon salt to the blender. Pulse just until the ingredients are incorporated and you have a thick, smooth batter. Don't overmix or your waffles will be tough.
Preheat your waffle maker according to manufacturer instructions. Pour batter onto the hot waffle iron (amount depends on your waffle maker size) and cook according to your machine's settings until golden brown and crispy. Let them cool slightly before serving to allow the texture to set perfectly.
