In a large bowl, mix the mashed potatoes with eggs until well combined.
Add in the cheese and flour. Stir the mixture together until perfectly smooth.
Divide the mixture into 18 equal parts. Shape each part into a flat pancake shape. Preheat a pan with oil over medium heat. Cook pancakes until golden brown and crispy (about 3 minutes).
Place the potato pancakes to rest on a plate lined with a paper towel. Serve with your favorite toppings and enjoy.
