Preheat the oven to 400 degrees F and prepare a baking sheet with parchment paper.
Put the flour, baking powder, salt and garlic powder in a food processor and pulse a few times to combine. Add the cold butter and pulse until the dry ingredients and the butter are mostly combined. (If you do not have a food processor, this can be done with a pastry cutter.)
Add the Parmesan, parsley, oregano and thyme. Drizzle in the milk and pulse (or stir in with a wooden spoon) until the mixture has just turned into a dough. Be careful not to overmix, as the biscuits will become tough when baked if you do.
Using 2 large spoons, drop 1/2-cup sized balls of dough onto the prepared baking sheet. This will make 6 generously sized biscuits.
Bake until golden brown, about 20 minutes, depending on your oven. Brush the warm biscuits with the melted butter. Enjoy!
