Preheat oven to 425°F and line a baking sheet with parchment paper. Set aside.
In a large mixing bowl, combine all-purpose flour, baking powder, granulated sugar and salt.
Add cold butter to the mixing bowl. Using a pastry cutter, fork or your fingers, cut the cold butter into the dry ingredients until coarse.
In the same bowl, add the milk, vanilla extract and crushed mini eggs. Mix the dry and wet ingredients together until dough begins to form.
Turn the dough out onto a lightly floured surface. Using your hands, press the dough together and form it into a disk about 1 ½ inch thick. Do not knead or overwork the dough.
Dip a scone cutter into flour and cut into the dough in one swift motion. Do not twist the cutter as this can seal the edges and prevent them from rising properly. Alternatively, you can cut the dough into wedges with a knife. Depending on the size of your scone cutter or how you cut the dough into wedges, you should get 6-8 scones. Place scones on the lined baking sheet.
Brush the top of each scone lightly with more milk then sprinkle with granulated sugar.
Bake the scones in a preheated oven for 15 minutes or until the edges and tops are lightly golden brown. Enjoy warm with butter or clotted cream and jam.
