Preheat the oven to 200°C (390°C). Grease and line a baking tray with parchment paper.
Sift the flour and baking powder together into a large mixing bowl with the sugar, salt, and butter.
Use your fingertips to rub the butter into the flour.
Make a well in the center of the mixture and pour in the buttermilk.
Use a knife, to cut the buttermilk into the flour, until it forms a soft sticky dough.
Tip the dough out onto a lightly floured work bench and quickly and gently knead to a ball.
Use your hand to press the dough out to an even 2 cm (0.78 inch) thickness.
Use a 5 cm (2 inch) cookie cutter to cut out as many scones as you can. Place each cut scone into the prepared tray so that they a spaced slightly apart.
Scrape the remaining dough together and repeat the pressing and cutting again.
Brush the tops with buttermilk.
Bake in the oven for about 15 – 20 minutes or until the tops turn golden brown.
Serve warm with butter or jam and cream.
