Gather the ingredients.
Heat the oven to 400 F (200 C/Gas Mark 6).
Place the mashed potatoes in a large bowl and add all the other ingredients to form a sticky dough.
Roll out the dough on a floured surface to approximately ½-inch thickness.
Cut into saucer-sized rounds then score a cross into the dough to mark 4 equal wedges.
Grease a baking sheet with butter and bake the scones for 20 minutes until golden brown and risen.
The scones can also be cooked on the stovetop on a griddle or heavy-based frying pan . Cook the scones 5 minutes on either side until golden and risen.
Serve with butter and eat warm. Enjoy!
