American Chocolate Chunk Cookies

*IMPORTANT AMENDMENT 24 MAY 2009- left out the sugar in the original post, SORRY! Thank you Michelle for bringing it to my attention :)

THE single best chocolate chip cookie recipe I have ever come across, so perfectly gooey and chewy and buttery that my friend thought "juicy" was the most appropriate word. Can't remember now which book or magazine it's originally from, but thank you so much to whoever came up with this decadent combination!

Melt together* and let cool:

100g dark chocolate

85g butter

*You can use a traditional bain marie method, but I find it saves time and produces the exact same result to microwave at full power, stopping every 20-30 seconds to stir until melted and glossy.

Beat in with a spoon until well mixed:

100g brown sugar

100g crunchy peanut butter

1 egg

1/2 tsp vanilla

Stir in:

100g self-raising flour

100g milk chocolate chunks

200g dark chocolate chunks

100g salted roasted peanuts

Drop tablespoonfuls (or roll into a medium ball in your hand and press) onto a baking sheet, leaving enough room for each cookie to spread. Bake 12 mins at 180 C (160C fan-assisted), or longer if you want crisper cookies. Flavour improves when stored overnight.
