Preheat oven to 375°F and line a baking sheet with parchment paper
Add the flour, baking powder, salt, spices, sugars, and butter to the bowl of a food processor and pulse together until the butter is broken up and only small pieces remain. The mixture will look crumbly.
Slowly add in the milk, continuing to pulse until the dough comes together.
Remove the dough from the food processor and fold in the apples by hand.
Gently roll out the dough on a lightly floured surface until it is about 1 inch thick. Cut out 6 scones with a 3 inch biscuit cutter.
Place the scones on the prepared baking sheet and bake for about 20 minutes until risen and starting to turn slightly golden on top.
Remove from the oven and allow the scones to cool before glazing.
To make the glaze, whisk the powdered sugar, milk, and vanilla extract together until smooth. Gently dip the scones into the glaze, and turn them over onto a rack and let the glaze harden.
Sprinkle a little nutmeg on top of the glazed scones, if you like (I like.)
Notes
Scone dough is not like bread dough...the less your work it, the better. After you add the liquid, blend it just until it comes together. When you turn it out onto a lightly floured board you can bring it together further with your hands.
