In a blender or small food processor, blend CHEETOS® FLAMIN' HOT® Cheese Flavored Snacks until finely ground. Add breadcrumbs and salt; pulse to combine. Transfer to a shallow bowl.
Toss halved mozzarella sticks with flour. Dip into beaten eggs, then dredge in bread crumb mixture until well coated, repeating egg and bread crumb mixture once.
Transfer to a parchment paper–lined resealable container; freeze for at least 4 hours or overnight.
Preheat oven to 425ºF. Arrange cheese sticks on a parchment paper–lined baking sheet, about 2 inches apart. Spray with cooking spray. Bake, turning pan halfway through, for 8 to 10 minutes until golden brown and crispy.
Serve with Marinara sauce or Caesar dressing for dipping.
Tip: Mozzarella sticks can be made in advance, then frozen in a resealable container for up to 2 months.
