Add the butter and sugars to a bowl and beat until creamy
Add in the egg and vanilla and beat again.
Add the blue food colouring and mix
Add in the plain flour, baking powder, bicarbonate of soda, and salt and beat until a cookie dough is formed
Add in the chocolate chips, chopped oreos and chopped cookies and mix briefly to combine
Split the cookies out into eight cookie dough balls - they're about 115g each
Once they're rolled into balls, place the cookie dough in the freezer for at least 30 minutes, or in the fridge for an hour or so
Whilst the cookie dough is chilling, preheat your oven to 200ºc/180ºc fan
IMPORTANT - if your oven usually runs HOT and browns things, you will need to lower the temp so it doesn’t brown the cookies. If you are worried, test bake ONE cookie and adjust accordingly
Take the cookies out of the freezer/fridge and put onto a lined baking tray. I put four cookies per tray
Bake the cookies in the oven for 11-13 minutes.
When fresh out of the oven - press in any extra bits for decor
I add half a cookie and use white chocolate chips to stick down the eyes (they melt on the hot cookie) and a few extra bits of biscuit
Let the cookies cool on the trays for at least 30 minutes, as they will continue to bake whilst cooling!
Notes
These are best eaten on the day of baking, but can be revived by microwaving for 15-30 seconds, or putting into a hot oven for 2-3 minutes!
Once baked, these will last for 4-5+ days
You can use chocolate bars chopped up instead of chocolate chips, just make sure the chunks aren't too big
These can freeze raw before baking for 3+ months, just add 1-2 minutes baking time.
