Shape Puffs:
Shape the mixture into small balls or patties and place them on the prepared baking sheet.
For extra crispiness, roll the potato cheese puffs in bread crumbs if desired.
Bake:
Bake in the preheated oven for 20-25 minutes, or until the cheese puffs are golden brown and crispy on the outside.

Customize the cheese puffs by adding other ingredients such as bacon bits, chopped herbs, or diced ham.
For a crispy exterior, you can also fry the cheese puffs in a skillet.
