Preheat oven to 400 degrees.
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 2/3 cup.
Add the milk, egg and chocolate chips 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.
Bake for 15 to 20 minutes.
