Cut 1/2 inch slices of mozzarella from the short side of the block of cheese.

Cut hearts or circles out of the center of the mozzarella sticks (approximately 1 inch in width). Space them about 1/2 inch apart from each other. You should be able to fit three holes.

Place mozzarella sticks on a sheet tray with parchment paper

Fill holes with your favorite sauce(s) and fillings to the top of the cheese. As an example, we used 1/3 cup marinara sauce and 4 oz of chopped pepperoni.

Place the baking sheet inside the freezer for at least 1 hour until completely frozen. 2 hours would be ideal.

Remove from the freezer and let the baking sheet sit for 5 minutes on the countertop.

While allowing the mozzarella sticks to sit, prepare the dredging station where you will bread them.

Beat 4 eggs into one bowl. Add 1/2 cup corn starch and 1/2 tsp salt and 1/2 tsp ground pepper to another bowl. Add 1 1/2 cups crushed cornflake breadcrumb, 2 tsp salt, 2 tsp granulated onion, 2 tsp granulated garlic, 1/2 tsp ground pepper.

Coat frozen mozzarella in corn starch, then eggs, then breadcrumbs, then eggs, and then breadcrumbs again. Shake off the excess between each coat.

Let coated mozzarella sit for 5 minutes to the side. We placed them directly into the deep fryer, three at a time.

Preheat deep fryer oil (according to your appliance's instructions) in the pot to 345F (175C).

Gently drop the mozzarella sticks in oil for 2 minutes until golden brown.

Place a wire rack on a paper towel-lined sheet pan while these are frying.

When the mozzarella sticks are done frying, remove them from the deep fryer basket or pot and place them on the wire rack. Let mozzarella sticks cool for for 2-3 minutes. Serve and enjoy!
