Preheat the oven to 180C/350F. Line a large baking tray with parchment paper and set aside.
In a large mixing bowl, combine all the ingredients and mix well, until a thick batter remains. Fold through the chocolate chips.
Form 12 balls of dough and place them on the lined tray. Bake the cookies for 10-12 minutes, or until the edges are just baked.
Remove the cookies from the oven and let cool completely.
