In a large bowl, place the cold mashed potatoes. Add shredded cheddar, eggs, flour, salt, pepper, and garlic powder. Mix thoroughly with clean hands until creating a thick, slightly sticky dough that holds shape when pinched. If too wet, sprinkle additional flour; if too dry, add a small amount of milk.

Scoop approximately 15 ml (one tablespoon) of dough and roll between palms into balls roughly the size of a ping pong ball. Maintain one hand dry for handling dough and the other for breadcrumb coating to prevent clumping.
03 -
Roll each dough ball evenly in panko breadcrumbs, pressing gently to ensure full coverage. Place coated puffs on a parchment-lined baking tray, spaced evenly.
04 -
Refrigerate the shaped and coated puffs for 10 minutes to help maintain shape during baking.

Preheat oven to 200°C. Bake the puffs on the middle rack for 20 to 25 minutes, until golden-brown and crisp on the outside with a melty interior.
