Creating these tasty Mashed Potato Cheese Puffs is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.
2. Mix Ingredients: In a large bowl, combine the mashed potatoes, shredded cheese, eggs, flour, Parmesan cheese (if using), garlic powder, onion powder, salt, and pepper. Mix well until thoroughly combined.
3. Shape Puffs: With your hands, scoop out portions of the mixture and shape them into small balls or puffs, about 1-2 inches in diameter.
4. Arrange on Baking Sheet: Place the shaped puffs onto the prepared baking sheet, leaving some space between each one.
5. Bake: Bake in the preheated oven for 25-30 minutes or until the puffs are golden brown and crispy on the outside.
6. Optional Frying: If you prefer a deep-fried version, heat oil in a frying pan over medium heat. Carefully place the puffs into the hot oil and fry until golden brown. Remove them with a slotted spoon and drain on paper towels.
7. Cool and Serve: Allow the cheese puffs to cool slightly before serving.
