Giving in to the excesses of the season, I used my 'best' brownie recipe, which gives dense, sweet and chewy brownies. The recipe comes from a 2000 edition of Good Food magazine, but I've never seen it on their website.
I doubled the recipe and stirred 100g of chopped walnuts and 100g of chopped fudge into the batter. This was so that CT could have half the batch, to start his Christmas eating with some home cooking. I used Lindt cooking chocolate which gave a really dark colour to the brownies. I'd forgotten how good these brownies are! And how rich - I could only eat half a portion at a time!
