Preheat your oven to 400°F / 200°C and line a baking sheet with parchment paper.
In a medium bowl, whisk together the almond flour, coconut flour, salt, and a pinch of garlic powder.
Set aside.
In a separate small bowl, combine the warm water, coconut sugar, and yeast.
Let it stand for 2-5 minutes until the yeast becomes foamy and activated.
Pour the yeast mixture and olive oil into the dry .
Stir to combine.
Gently fold in the beaten egg whites and the grated mozzarella cheese until the batter is well-incorporated.
Pour the mixture onto the prepared baking sheet and use a spatula to shape it into a rustic flatbread or loaf shape, about half an inch thick.
Bake for 15 minutes, until the bread is firm and golden brown.
While the bread is baking, prepare the topping by mixing the melted butter with the remaining garlic powder and salt.
Remove the bread from the oven, brush it generously with the garlic butter mixture, and return it to the oven to bake for another 5-10 minutes until sizzling and fragrant.
Mix 1 tablespoon (15 ml / 0.5 fl oz) of fresh chopped parsley or Italian seasoning into the garlic butter topping for a burst of fresh herb flavor.
