Preheat oven to 375 degrees.
In a large mixing bowl, combine the dry ingredients (flour, oatmeal, sugar, baking powder, salt, cinnamon and nutmeg.) Using a pastry cutter or forks, cut in the butter to the dry ingredients. Add the milk and continue to mix. The dough will become crumbly and slightly sticky. Lastly, fold in the apple chunks into the batter. Stir just until the apples are evenly distributed into the dough.
Turn the dough out on to a lightly floured surface, shaping it into round disk, approximately 10 inches wide, by 1 inch thick (give or take, just an estimate). Cut the dough into 6 triangles. (You could also cut into 12 mini scones.) Transfer the scones on to a baking sheet, and bake for 22-25 minutes at 375 degrees, baking to a golden brown. Cool for a few minutes before glazing.
For glaze: In a small bowl combine the powdered sugar and cinnamon using a fork or small whisk. Gradually add in the milk, stirring until smooth. Drizzle the scones with the glaze. Enjoy!
