Use your larger heart cookie cutter to cut a heart shape out of all your chunks of mozzarella cheese and then use your smaller cookie cutter to cut smaller heart shapes out of the middle of each one.
Set up a dredging station with three bowls — flour in the first one, eggs and milk in the second one and crushed Flamin’ Hot Cheetos in the third one.
Coat each mozzarella cheese heart in flour, submerge in egg wash and cover in crushed Flamin’ Hot Cheetos. Repeat this step a second time if necessary and freeze for at least an hour.
Heat oil in deep fryer or heavy skillet to 375°F and fry Flamin’ Hot Cheetos Breaded Mozzarella Cheese Sticks for 4 minutes.
Drain on paper towels and serve with ranch or your preferred dipping sauce.
