In a mixing bowl, combine your chilled mashed potatoes, shredded cheese, eggs, salt, and pepper. Use a fork or spatula to blend the ingredients until smooth.

With hands lightly coated in oil or water, scoop out portions of the potato mixture. Shape each portion into small balls or patties.

Prepare a plate with seasoned breadcrumbs. Roll each puff in the breadcrumbs, ensuring they're fully coated.

Preheat your oven to 400°F (200°C). Arrange the coated potato puffs on a baking sheet lined with parchment paper and bake for 20-25 minutes.

Once baked, remove the puffs from the oven and let them cool for a few minutes. Serve warm with your favorite dipping sauces.
