Instead of cake we had brownies to celebrate S's 30th birthday. Let's face it, brownies are so much better. I used Nigella's recipe from How to be a Domestic Goddess. If this is the ultimate brownie, then consider this the ultimate indulgence. Just reading the list of ingredients is likely to increase your waist line by a good few inches. This is a very special occasion brownie, and man is it a treat worth waiting for.
