Cheesy Mashed Potato Puffs

Preheat your oven to 375°F (190°C). Grease or line a muffin tin with paper liners.
Prepare the Potato Mixture:

In a large mixing bowl, combine the mashed potatoes, shredded cheddar cheese, Parmesan cheese, eggs, milk, green onions, garlic powder, smoked paprika (if using), and salt and pepper. Mix everything together until well combined.
Form the Puffs:

Spoon the mashed potato mixture into the muffin tin, filling each cup about 3/4 full. You can smooth the tops with a spoon or leave them slightly uneven for a rustic look.
Bake:

Bake in the preheated oven for about 20-25 minutes, or until the tops are golden brown and crispy.
Serve:
