Preheat oven to 350 F. Combine the almond flour, baking powder, sea salt, psyllium husk powder, and garlic powder in a mixing bowl. Use a whisk to combine the ingredients. Prepare an 8″ x 8″ pan with nonstick cooking spray.
Next, add in the eggs and egg whites. Then add the olive oil. Whisk well to incorporate the ingredients.
Pour the dough into an 8” x 8” pan that has been sprayed with nonstick cooking spray. Bake 25 minutes or until puffed and cooked through. Gluten-free bread tends to bake for a longer amount of time, so if unsure, err on the side of adding a couple of extra minutes.
In the meantime, melt the butter in a bowl and add ¼ tsp garlic powder and ¼ tsp kosher salt. Spread this mixture over the top of the cooked bread.
Then top the bread with parmesan cheese and mozzarella. Next, sprinkle the Italian seasoning over the top. Broil the bread with the cheese for 2-3 minutes or until nicely browned. Cut and serve immediately!
