To make the scones: Combine the flours, oats, sugars, baking powder, and salt in a large mixing bowl. With a pastry cutter
or a fork, cut the butter into the dry ingredients until the butter pieces are the size of a pea. Stir in the macadamia nuts. Whisk together the egg, milk, and almond extract in a large measuring cup. Make a well in the center of the dry ingredients, and add the liquid all at once to the bowel. Lightly mix with a fork until the dough is evenly moistened; it will comes together but still be a little wet. Don't stir vigorously, or the scones will be tough. Let the dough sit for 5 minutes to allow the oats to absorb the liquid.
