Cut the mozzarella cheese into half-inch strips.
Dip the mozzarella sticks in the flour, then the egg mixture, and finally the breadcrumb mixture to create a triple seal.
Freeze the mozzarella sticks for 30 minutes to 1 hour.
Prepare the ranch dip by mixing mayonnaise, sour cream, ranch seasoning dip mix, buttermilk, and dill weed.
Fry the mozzarella sticks at 350°F until golden brown.
Toss the fried mozzarella sticks in a bowl with the melted sugar mixture to coat them.
