Triple Chocolate Cookies

I got my hands on my Nanny's triple chocolate cookie recipe. There's few things better than a freshly baked cookie with a cold glass of milk and these tick all the boxes. They have that light crisp exterior and a slightly chewy centre, the way all cookies should be in my opinion. These hit all three major food groups, milk, dark and white chocolate, keeping everyone happy. (I'm only winding when I say that), but we all deserve a wee treat now and again and these definitely satisfy it.
