Preheat the oven to 400℉. Whisk together the flour, sugar, baking powder, and salt.
Cut in the butter until the pea-sized, then whisk together the egg and ½ cup of the milk and add into the dry ingredients. Continue slowly adding milk until the dough just holds together.
Roll out the dough on floured surface, then fold the dough over in half and roll out again. Repeat this process 2-3 more times, leaving the dough about ½ inch thick.
Use a circular biscuit cutter to cut out the scones and place on a baking tray lined with parchment paper.
Bake for 12 minutes or until the tops are golden brown. Remove from the oven and brush with butter.
Slice in half and enjoy with jam and whipped cream or topping of choice.
