Preheat your oven to 400°F (200°C). Line a baking tray with parchment paper.

In a mixing bowl, combine the mashed potatoes, cheddar cheese, beaten eggs, flour, salt, black pepper, and garlic powder. Mix until just combined.

Scoop a portion of the mixture and roll it into a ball about the size of a ping pong ball. Continue until all mixture is shaped into balls.

Roll each ball in breadcrumbs until fully coated.

Place the coated puffs onto the prepared baking sheet with enough space between each.

Bake for 20-25 minutes until golden brown and crispy.

Remove from oven and let cool for a few minutes. Serve warm with dipping sauces.
