Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.

In a mixing bowl, combine the flour, Parmesan cheese, baking powder, garlic powder, and salt.

In a separate bowl, whisk together the melted butter, beaten egg, and milk.

Pour the wet ingredients into the dry ingredients and mix until just combined.

Using a spoon, drop small mounds of the mixture onto the prepared baking sheet, spacing them about 2 inches apart.

Sprinkle the tops with black pepper and bake for 15-20 minutes or until golden brown.

Remove from the oven, let cool slightly, and garnish with chopped parsley before serving.
