Preheat oven to 400°. Line a baking sheet with parchment paper.
In a large bowl, whisk together flour, baking powder, salt, ½ teaspoon pepper, sugar, and garlic powder. Stir in buttermilk and frozen butter just until a sticky dough forms. Drop dough by heaping ⅓ cupfuls 2 inches apart onto prepared pan; sprinkle with remaining ¼ teaspoon pepper.
Bake for 15 minutes. Brush with melted butter, and bake until golden brown, about 5 minutes more. Let cool on pan for 5 minutes; serve warm.
