Preheat your oven to 400°F (200°C). Lightly grease a 12-cup muffin tin with cooking spray or butter to prevent sticking.

In a large mixing bowl, combine the mashed potatoes, shredded cheddar cheese, grated Parmesan cheese, eggs, milk, chopped green onions, garlic powder, and smoked paprika (if using). Season with salt and pepper to taste. Stir well until all ingredients are thoroughly combined and the mixture is smooth and creamy.

Using a spoon or ice cream scoop, divide the potato mixture evenly among the prepared muffin cups. Fill each cup about three-quarters full to allow room for the puffs to rise during baking.
04 -
Place the muffin tin in the preheated oven and bake for 20-25 minutes, or until the tops are golden brown and the puffs are set in the center. The edges should be crispy and slightly pulled away from the sides of the muffin tin.
05 -
Remove the muffin tin from the oven and let the potato puffs cool in the tin for about 5 minutes. This brief cooling period helps them set up and makes them easier to remove without breaking.

Carefully run a knife around the edges of each puff to loosen, then gently lift them out of the muffin tin. Serve warm as a side dish, snack, or appetizer. They're delicious on their own or with a dollop of sour cream or a sprinkle of additional green onions.
