Recipe for charcoal cookies

Yup, I made them and they take merely four hours to bake.
Easy.
Here's how you do it.
Take all your usual ingredients for really good quality chocolate chip cookies: organic butter, soft brown muscovado sugar, spelt flour, Green & Blacks dark chocolate, organic eggs and so on.
Make two batches of these cookies and then let them cool on wire racks in the kitchen whilst popping the last batch in the oven for a quick ten minutes.
And here is where you raise your game from cook to kitchen genius.
Forget this last batch and sweep yourself and your family off into Colchester for lunch.
Meet D-Mamas and friends with D for lunch as part of the support group you help run and chat merrily away.
Order coffee, order falafel and salad, have more coffee. Stroll back to the van and drive home feeling great about knowing such lovely people.
Open the front door, smell the burnt fat and think "Oh, damn, I left the oven on".
Walk slowly to the oven and look inside, still expecting to see nothing in there, because really, what kind of fool leaves cookies for four hours!?!
Find this:

Slap your forehead and know for a fact that you are the biggest muppet of a cook since the Swedish chef on the Muppet Show and spend three days trying to get the dark stains off the tiles and the smell out of the house.
Put the cookies in the bin outside, because even the compost would surely be poisoned by this travesty.

Happy eating!
