Mix flour, baking powder and salt in a large bowl. Rub in the cold butter. Pour in the milk and quickly stir into a sticky dough.
Generously flour your work surface. Toss the dough in the flour (no kneading!) until it's not sticky anymore. Cut into 12 equal pieces and chill in the fridge.
In the meantime, mix the dried herbs, garlic, salt and melted butter in a medium bowl. Add the grated parmesan to a second bowl.
Heat the oven to 400°F. Lightly grease a 12 city muffin tin with a little of the butter-herb mix.
Roll every piece of chilled dough into three small balls. Toss in the melted herb butter, then coat with grated parmesan. Add three coated dough balls in every muffin tin cavity.
Bake for 15 minutes or until golden brown. Cool in the pan for 5 minutes, then transfer to a cooling rack.
