In a bowl, mix cream cheese, cheddar cheese, mozzarella cheese, garlic powder, onion powder, salt, and pepper until well combined.

Use your hands or a small scoop to form the cheese mixture into small 1-inch balls.

Set up a station with three bowls—one with flour, one with the beaten eggs, and one with a mixture of panko breadcrumbs and Parmesan cheese.

Dredge each cheese ball in the flour, dip it in the eggs, and roll it in the breadcrumb mixture to coat completely.

Heat oil in a deep fryer or large pan to 350°F (175°C).

Fry the cheese balls in small batches until they are golden brown and crispy, about 2-3 minutes per batch.

Use a slotted spoon to remove the cheese balls from the oil, and drain them on paper towels. Serve warm!
