Preheat oven to 400°F and spray or lightly oil a baking sheet.
In a large bowl, whisk together flour, baking powder, sugar and salt. Toss butter into the dry ingredients until coated with flour. Working quickly, either:
Add milk and toss with a fork until it just comes together into a slightly sticky, shaggy dough. With a knife, and handling as little as possible, divide dough into 8 pieces.
Place lumps, patting them slightly into a round shape (lumpy top is fine) and handling them as little as possible, on baking sheet and bake for 14 to 18 minutes until golden brown. Serve immediately.
