Preheat the oven to 375°F and place the oven rack in the middle level of the oven. Line a baking sheet with parchment paper or lightly grease a large muffin tin; set aside.
In a bowl, combine flour, sugar, baking powder, garlic powder, and salt. Smash in the butter with a fork.
Mix in the milk a little at a time; stir using a rubber spatula just until a moist and sticky dough forms. Gently fold in parsley.
Portion the dough evenly onto the prepared baking sheet or muffin tin. Place into oven and bake for 12-15 minutes, or until cooked in the center and serve. A toothpick inserted into the center should come out clean.
