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

Grate the potatoes using a grater or food processor.

Squeeze out excess moisture from the grated potatoes using a clean kitchen towel.

In a mixing bowl, combine the grated potatoes, flour, cheese, egg, baking powder, salt, and pepper.

Lightly grease the preheated waffle maker with oil.

Pour a ladleful of the potato mixture into the waffle maker and spread it evenly.

Cook for about 5-7 minutes or until golden brown.

Carefully remove the waffle using a spatula and place it on a plate.

Repeat with the remaining batter.

Serve hot with your favorite toppings.
