In a mixing bowl, whisk together the flour, baking powder, and salt.

In another bowl, combine the cottage cheese, eggs, milk, vanilla extract, and melted butter.

Pour the wet ingredients into the dry ingredients and stir until just combined.

Preheat the waffle iron according to the manufacturer's instructions.

Pour the batter onto the preheated waffle iron and cook until golden brown, about 5 minutes.

Repeat with the remaining batter.

Serve the waffles warm with your choice of toppings such as syrup, fruit, or yogurt.
