To prepare, preheat your oven to 200°C and line a baking sheet with parchment paper.
In a medium bowl, combine the flour, baking powder, salt, and sugar. Cut the butter into small cubes, transfer it to the bowl, and start rubbing the butter into the flour until you get a mixture that resembles coarse breadcrumbs. Pour in the milk and use your fingers to mix it together until it becomes a dough. Press and knead briefly.
