Preheat your oven to 400°F (200°C). Generously grease a mini muffin pan with butter or cooking spray to prevent sticking.
In a large mixing bowl, mix the chilled mashed potatoes with shredded cheddar cheese, chopped chives, all-purpose flour, garlic powder, salt, and pepper. Crack the egg into the bowl and stir thoroughly until everything is evenly mixed.
Use your hands or a small cookie scoop to form the potato mixture into 1-inch balls. Roll each ball in grated Parmesan cheese for a crispy coating. Place each ball into a cup of the greased muffin pan, pressing gently to shape them into the mold.
Place the muffin pan in the preheated oven and bake for 15-20 minutes, or until the edges of the puffs turn golden brown and crispy. Keep an eye on them to prevent overcooking.
Let the puffs cool in the pan for a few minutes before removing. Serve warm for the best flavor and texture.
Notes
For extra flavor, try adding a pinch of paprika or cayenne to the potato mixture. These puffs can be made ahead and reheated in the oven.
