These cookies are indeed very lovely punishments: flaky, crumbly and not too sweet. Just the type of cookies I love: you can munch them with your coffee or tea or with milk. Very plain, but very scrumptious at the same time and utterly Parisian I'd say. You'll need only 4 ingredients, which you probably already have in your pantry. (Use good-quality products as it really makes a difference when there is so few ingredients.)
