Preheat oven to 400 degrees. In a large bowl, combine the flours, sugar, baking powder, salt and cinnamon; mix well. Cut the butter into the flour mixture until it resembles small peas. Break the egg into a 1-cup measure and add milk to make ⅔ cup. Add the milk, egg and chocolate morsels to the flour mixture and combine lightly until a loose ball is formed. A light hand makes for a light scone. Hand knead the mixture in the bowl 5 to 10 times and then break into 2 equal portions. Press down each ball on an ungreased cookie sheet to form a 6-inch disc. Score each disc into 6 wedges. Brush with a wash of egg whites or heavy cream. Bake for 15 to 20 minutes.
