In a large mixing bowl, add your ingredients, except for the chocolate chips, and mix well. Fold through the chocolate chips.
Cover the bowl and place it in the refrigerator for 2 hours, to firm up.
Preheat the oven to 180C/350F. Line a large baking sheet with parchment paper and set aside.
Remove the cookie dough from the refrigerator and form 12 balls with the dough. Place the balls of dough on the lined sheet and bake in the oven for 10-12 minutes, or until the edges are just golden.
Remove the cookies from the oven and let them cool on the sheet completely.
