Preheat your oven to 400°F and grease a muffin pan. This is key to ensure the puffs come out easily.
In a large bowl, combine the mashed potatoes, beaten eggs, cheddar cheese, and chopped chives. Don’t forget to season with pepper to taste.
Now, take a spoon and scoop a generous heaping spoonful of the potato mixture into each cup of the muffin pan.
To make it even more scrumptious, top each muffin with a sprinkle of shredded Parmesan cheese.
Bake those beauties for 30 to 35 minutes, or until they’re a lovely golden brown and crispy on top.
After baking, allow the potato puffs to cool for about 5 minutes before you remove them from the muffin pan. Patience is key!
Serve them warm with a dollop of sour cream on top for that extra creamy goodness.
Enjoy these delightful mashed potato puffs as a side dish or appetizer!
