Let’s dive into creating these delightful bites of bliss. Here’s how:

1. In a large mixing bowl, combine the mashed potatoes, cheddar cheese, Parmesan cheese, and egg. Mix until well combined.
2. Add the flour, garlic powder, salt, and pepper to the potato mixture. Stir until the mixture forms a thick dough-like consistency.
3. If using, fold in the chopped chives. This adds a lovely pop of color and flavor.
4. Heat about 2 inches of oil in a large skillet over medium heat. You’ll know it’s ready when a small piece of bread browns in about 60 seconds.
5. Using your hands, shape the potato mixture into small balls, roughly the size of a golf ball. If the mixture feels sticky, dust your hands with a bit of flour.
6. Carefully place the balls into the hot oil, frying them in batches to avoid overcrowding. Fry until golden brown and crispy, about 3-4 minutes per side.
7. Remove the puffs with a slotted spoon and drain them on a paper towel-lined plate.
8. Serve warm, and watch them disappear!

It’s important to keep an eye on the oil temperature; too hot, and you’ll have burnt outsides and raw insides. Too cool, and your puffs will absorb too much oil. It’s a delicate dance, much like getting the kids to bed on time!
