The Ultimate Chocolate Cookies

I went to watch Toy Story 3 with a friend last weekend and thought I would make something special (ie something really unhealthy and full of butter and sugar) to share. I remember this recipe from Nigella Express. These cookies are an absolute form indulgence. Really rich and moist and loaded with chocolate richness in every bite. They've got melted dark chocolate, cocoa powder AND dark chocolate chips. So rich it would literally make your stomach sick.

The Ultimate Chocolate Cookie

125g dark chocolate
150g plain flour
30g cocoa powder
1 tsp baking soda
1/2 tsp salt
100g butter, at room temperature
60g brown sugar
1 tsp vanilla extract
1 egg, cold from the fridge
110g dark chocolate chips

1) Preheat oven to 170 degrees C. Melt the 125g dark chocolate in a heatproof dish over a pan of simmering water.
2) Combine the flour, cocoa, soda and salt into a mixing bowl.
3) Cream the butter and sugar in another bowl. Add the melted chocolate and mix together.
4) Beat in the vanilla and cold egg. Then mix in the dry ingredients. Stir in chocolate chips.
5) Place tablespoonfuls of batter on a lined baking sheet. Do not flatten.
6) Bake for approx. 15 minutes, testing with a cake tester to make sure it comes out semi-clean and not wet with batter. The cookies will not set completely as they will harden while cooling.
7) Leave to cool slightly on the baking sheet for 4-5 minutes, then transfer them to a cooling rack.
