Cook macaroni according to package instructions, then drain and set aside.

In a large saucepan, melt butter over medium heat. Stir in flour and cook for 1 minute.

Gradually whisk in milk, cook until mixture thickens, then add cheeses and stir until melted.

Combine cheese sauce with cooked macaroni and mix well. Let it cool in the refrigerator for 30 minutes.

Form the mixture into 1.5-inch balls. Dip each ball into beaten eggs, then coat with bread crumbs.

Heat vegetable oil in a deep skillet over medium-high heat. Fry the balls until golden brown, about 2-3 minutes each side.

Drain on paper towels and serve hot.
