Follow these steps to create your amazing Mashed Potato Cheese Puffs:

1. Prepare Your Workstation: Begin by setting up your workstation with bowls for the mashed potatoes, flour, and breadcrumbs.
2. Mix Ingredients: In a mixing bowl, combine the cooled mashed potatoes, shredded cheese, flour, garlic powder, onion powder, and salt and pepper to taste. Mix until well combined.
3. Form the Puffs: With your hands, take small portions of the mixture and roll them into balls, about the size of a golf ball.
4. Beat the Eggs: In a separate bowl, beat the eggs until foamy. This will be used for coating.
5. Coat the Puffs: Dip each ball into the beaten eggs, allowing any excess to drip off. Then, roll them in breadcrumbs to coat evenly.
6. Heat the Oil: In a deep skillet or pot, pour in oil to a depth of about 2 inches. Heat the oil over medium heat until it reaches 350°F (175°C).
7. Fry the Puffs: Carefully add the puffs to the hot oil in batches. Fry them for about 2-3 minutes or until golden brown and crispy.
8. Drain Excess Oil: Using a slotted spoon, remove the puffs from the oil and place them on a paper towel-lined plate to drain any excess oil.
9. Repeat: Continue the frying process until all puffs are cooked.
10. Serve Warm: For the best experience, serve the Mashed Potato Cheese Puffs warm.

These step-by-step instructions will guide you to make puffs that are perfectly crispy on the outside and delightfully cheesy on the inside!
