Beat the butter till soft, add the sugar and beat till well mixed. I usually use a hand mixer.
Add the syrup, flour, chocolate chips and milk and mix well.
Grease two or three baking trays. Grab about a spoonful of mixture in your fingers at a time and roll into a 1 inch ball. Place on tray and squish flat.
Place in oven preheated to 180C/350°F Bake for 8-10 minutes. When finished immediately transfer to a wire cooling rack.
