You can summon the ancient one by wearing this t-shirt, mumbling some mumbo-jumbo, and doing the following:
To summon: Cream 125g butter into 1/2 cup brown sugar, 1/2 cup white sugar and 1/2 teaspoon of vanilla. Mix in beaten egg. Mix 1 3/4 cups sifted flour. Stir and add 1/2 cup choc chips and 65g crushed walnuts. Roll into teaspoon sized balls and bake for 10-12 minutes at 180 degrees.
Let me know how that works out for you.
