Instructions

1. Preheat oven to 180 C (350 F) standard / 160 C (320 F) fan-forced. Grease a 12 hole muffin tin well with butter.
2. In a large mixing bowl, beat the butter and sugars using an electric beater for a minute or two until pale and creamy. Add the egg and the vanilla and beat until combined. Add the sifted flour, baking soda and gently fold using a spatula or wooden spoon.
3. Divide the cookie dough into 10 even sized balls. Roll into a ball and pop in your prepared muffin pan. Repeat with remaining cookie dough. Press chocolate chips onto the top of each ball of cookie dough.
4. Place in the oven for 12 minutes or until the tops are golden brown. Let the cookies cool for about 15 minutes or so and then very gently run a butter knife around the edges of each one and lift the cookies out. Leave on a wire rack to cool.
