Nigella's Totally Chocolate Chocolate Chip Cookies

At this moment, I have 5 pieces of the mixture sitting in the fridge, waiting to be baked. I'm gonna share this recipe but since i have not copied the exact steps from the recipe book, if yours doesn't work..., go and buy the book lah!

125g dark chocolate
150g flour
30g cocoa, sieved
1tsp bicarbonate soda
1/2tsp salt
125g soft butter
75g light brown sugar
50g white sugar
1tsp vanilla extract
1 egg, cold
350g chocolate chips (very expensive investment!), semi sweet or dark

Steps

1. Heat the oven to 75 degrees C, melt dark chocolate in a bowl over simmering water.
2. Mix flour, cocoa, bicarbonate and salt together.
3. Cream butter with the sugars, add chocolate and mix thoroughly.
4. Beat in the egg and vanilla and then fold in the dry stuff. Finally stir in the choc chips. (at this point, mixing becomes very difficult!)
5. Scoop about 12 equal sized balls unto a baking sheet, 6 cm apart.
6. Cook for 30 mins, test with a skewer - it should come out semi-clean.
7. Remove from oven and let cool. It will harden a bit.

(Do not eat too much of this if you are the heaty type, it is very very very heaty!)
