Line enough baking trays to make 12 cookies. I usedfour baking trays but mine were pretty small and I wanted to make sure when thecookies spread they didn’t touch and leave to one side.
In a bowl mix together the sugar and butter until theyare combined.
Add in the vanilla, cornflour, flour and mix until allcombined. The mixture may be quite dry and may not stick together, if thishappens add in the milk one tablespoon at a time until the mixture combines.
Finally add in most of the chocolate chips and mixuntil they are evenly distributed. It should become one large ball of mixturein the middle of your bowl.(This is completely optional you can add all thechocolate chips if you want. You can roll your cookie dough balls in theremaining chocolate chips before you bake or you can sprinkle them over the topof your baked cookies.) Roll the mixture into ping pong sized balls and put onyour baking tray. Make sure they are spaced out you don't want them touchingwhen they spread in the oven.
Put the cookie dough balls in the fridge to cool for 30 minutes.
Preheat your oven to 180C (160F).
After your cookie dough balls have been in the fridgefor 30 minutes to chill put then in the oven for 5-10 minutes or until they areslightly golden around the edges. (If you are sprinkling your chocolate chips over the top do this once you take them out the oven, just be careful as the cookies will be super hot.)
Leave them to cool completely before trying to remove themfrom the baking trays. If they are still warm they might fall apart or stick tothe grease proof paper.
