Preheat oven to 400 degrees F. Line a baking or cookie sheet with parchment paper or silpat mat.
In a large bowl, whisk together the flour, cinnamon, nutmeg, baking powder, and salt.
Add the cubed cold butter to the dry ingredients and mix together with a pastry cutter or pastry blender. Cut the butter until the flour mixture forms coarse crumbs.
In a medium mixing bowl, whisk together the egg, vanilla extract, sugars, and buttermilk until combined.
Add the wet mixture to the dry mixture, then add the apples, and stir with a wooden spoon or spatula just until a dough is formed.
Place the dough onto a lightly floured surface and fold the dough just until combined in a ball. Gently flatten the dough ball with your hands or a rolling pin. If dough appears sticky, add more flour to the surface.
Roll the dough out to 9-10 inch diameter circle. Cut into 8 triangles using a sharp knife or bench scraper.
Place the scones on the prepared baking sheet and bake for 16-20 minutes, or just until lightly browned on the top.
