Cookie Dough;

• Beat the butter, icing sugar, brown sugar, vanilla extract and milk together.
• Beat in the flour and the mini chocolate chips.
• Roll the dough into 12 balls and place them on a tray in the freezer for at least half an hour.
• While the cookie dough is freezing, make the chocolate cookies.
• Preheat the oven to 180°C (350°F) and line a baking tray with baking paper.
• Beat the butter, brown sugar and sugar together until fluffy.
• Beat in the vanilla and egg.
• Finally beat in the cocoa, flour, baking powder and baking soda.
• Take the cookie dough balls out of the freezer and grab a chunk of the chocolate cookie dough.
• Flatten the piece of dough in your hands and place a cookie dough ball in the middle.
• Wrap the chocolate cookie dough around the ball and place on the baking tray.
• Repeat with the remaining dough.
• Bake the cookies for around 15 minutes. The cookies will have spread a little and the outside will still be soft but look set.
