Preheat your oven to 350 degrees and line a baking sheet with parchment paper.
In a bowl, combine 1 cup mozzarella, 1 cup Parmesan cheese, 1 egg and 1 teaspoon garlic powder, until well incorporated.

Place the mixture onto your parchment paper, and flatten it out like you would a pizza crust.
Bake for about 15 minutes, and then switch the oven to broil and move the baking sheet to the top rack for a few minutes to brown the cheese a little.
Slice with a pizza cutter, and enjoy!
