First, preheat your oven to 400°F (200°C) and warm up your mini waffle maker.
In a small bowl, whisk together the egg, almond flour, 1/2 cup mozzarella, Parmesan, Italian seasoning, and garlic powder until everything is well combined and smooth.
Once your mini waffle maker is hot, sprinkle a tiny bit of shredded mozzarella onto the griddle. Pour half of your prepared batter over the cheese, then sprinkle a bit more cheese on top. Close the lid and cook for 3-5 minutes, or until golden and crispy and your waffle maker indicates it's done. Repeat this process for the second mini pizza crust.
Carefully remove the crispy chaffle crusts from the waffle maker and place them on a baking sheet. Let them cool for a few minutes; this helps them stay firm and prevents toppings from making them soggy.
Once slightly cooled, spread a thin layer of low-carb pizza sauce on each chaffle crust. Top with additional shredded cheese and your favorite healthy low-carb pizza toppings.
Bake in the preheated 400°F (200°C) oven for 3-4 minutes, then turn on the broiler for an extra 1-2 minutes until the cheese is bubbly and lightly browned. Enjoy your easy, healthy mini pizzas!
