Preheat the oven to 450 degrees F (230 degrees C). Lightly grease a baking sheet.
Mix flour, sugar, baking powder, and salt together in a large bowl. Cut in cold butter with a knife or pastry blender until the mixture resembles coarse crumbs. Stir in milk, a little at a time, until dough is moistened. Drop dough by heaping spoonfuls onto the prepared baking sheet.
Bake in the preheated oven until golden, 12 to 15 minutes.
