                In a large bowl, mix together the flour, baking powder, and caster sugar. Using your fingers, rub in the cold butter until the mixture resembles coarse crumbs with pea-sized pieces of butter. Add the milk and mix until the dough comes together with a texture similar to soft cookie dough.
