Stir together sugar, flour, salt, and baking powder in a big mixing bowl. Blend the butter into the mix using your hands or a pastry cutter until it gets crumbly. Add the milk bit by bit and stir until you get a nice dough. If it's dry, splash in a little more milk. Wrap up the dough in plastic and toss it in the fridge for about 30 minutes.
