Preheat the oven and prepare for baking. (While the original source didn’t specify the oven temperature or bake time, a typical temperature is 200 °C / 400 °F.)

In a large bowl, combine the mashed potatoes, eggs, cheddar cheese, flour, garlic powder, salt, and pepper until well mixed.

Shape the mixture into bite-sized puffs or balls and roll them in breadcrumbs to coat completely.

Place the puffs on a baking sheet lined with parchment paper or lightly greased foil.

Bake until golden and crispy on the outside—typically around 20–25 minutes, flipping halfway (timing estimated based on standard baking for similar snacks).

Serve hot, optionally with your favorite dipping sauce (e.g., sour cream or aioli)
