Prepare the White Cheddar Mac and Cheese according to the recipe. Once cooked, let it cool in the refrigerator for at least one hour.
Form into small balls, about 1” in diameter, using a tablespoon of mac and cheese mixture for each ball. Place on parchment paper-lined baking sheet.
Heat oil in a deep saucepan over medium heat to 350-375°F degrees.
Place the flour and salt in a separate shallow bowl. Then, place eggs, panko breadcrumbs, and pepper into separate shallow bowls.
Dip mac and cheese balls into the flour first, then the egg mixture, and then, the breadcrumbs. Press lightly to make sure they are evenly coated. After that, sprinkle a pinch pepper into the balls.
Fry in batches of 8-10 balls for 2-3 minutes or until golden brown. Remove from oil with a slotted spoon and place on paper towels to absorb any excess oil.
