Heat oven to 180 c.

Cream together the Butter and both sugars - until well mixed dont need to disolve the sugar.

In a bowl mix egg and vanilla and whisk to combine.

In a large bowl, mix flour, baking soda, baking powder and salt to combine.

Add the butter and egg mixtures to the flour bowl and mix well so all flour incorporated. Do not over mix. Then add the choc chips - I use frozen as this helps keep the mixture cold. Put all bowl into fridge and chill for 10-15 mins.

Get 2 baking sheets / trays and line with baking paper (I also use a quick baking release spray optional) then take 2-3 tsp of mixture and place on tray - I only get 4 per tray as they spread out a lot. Bake for 8 mins or until just starting to turn slightly brown - then remove trays and allow to cool on a wire rack before removing them and then allow to cool for 20-30 mins. Repeat with all the mixture. I got 30 cookies :)

You can pack in a box separated by greaseproof paper and put in fridge and eat later - like that is going to happen ??? lol :P my family eat all within 2 days :) ENJOY :)
