- Preheat your oven to 375°F (190°C) and grease a 9x5-inch loaf pan. 
- In a large mixing bowl, combine the flour, baking powder, salt, garlic powder, black pepper, and Parmesan cheese. Mix well. 
- In a separate bowl, whisk together the melted butter and milk until combined. 
- Pour the wet ingredients into the dry ingredients and stir until just combined. Do not overmix. 
- Fold in the chopped parsley, basil, and red pepper flakes if using. 
- Pour the batter into the prepared loaf pan and smooth the top with a spatula. 
- Bake for 30-35 minutes or until the top is golden brown and a toothpick inserted into the center comes out clean. 
- Allow the bread to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
